BA.4 and BA.5, the new branches of Omicron with stronger communication power, have recently attracted attention. The new branch has triggered a new infection peak in South Africa, and the Portuguese National Institute of Health also estimates that its growth advantage is 13% more than that of BA.2.

Screenshots from the nextstrain website show that the different Omicron branches represented by yellow, orange and red are iterating rapidly within half a year, and the new branches represented by orange and red are also expanding in the cracks.

Screenshot of nextstrain website. According to the uploaded sequencing data, since December last year, the mainstream branches in Omicron have gradually changed from BA.1 (shown as 21K) to BA.2 (shown as 21L) to BA2.12.1 (shown as 22C), and the area occupied by new branches is also expanding.

The new branches of Omicron are frequent. Is the current COVID-19 vaccine still effective? Do the branches BA.2 and BA.5 need their own vaccines? Should the update of COVID-19 vaccine keep up with the variation of virus? How to keep up with the virus mutation? With the above questions, the reporter of Science and Technology Daily contacted and interviewed a number of industry experts.

Is the current vaccine still effective?

Does the mutation branch in Omicron constantly trigger new infection peaks, which means that the current COVID-19 vaccine will be invalid?

Authoritative experts in the industry responded to the Science and Technology Daily reporter and said: "Current vaccines can still provide the most basic protection in ensuring the reduction of severe illness and death.. The epidemic in COVID-19 has been going on for two and a half years. At present, it seems that there is no possibility for Covid-19 to achieve zero infection through vaccination. COVID-19 vaccine can ensure the effect of reducing infection and avoiding serious illness and death. "

Regarding the role of the current vaccine in epidemic prevention and control, the person in charge of vaccine-related production enterprises in COVID-19 holds the same view: "The existing vaccine is no problem in preventing severe illness and death at present, but it will not be 100% anti-infection."

Many statistics or research results from the real world show that the current vaccine plays a significant role in preventing severe illness and death. For example, the latest data in Hong Kong (as of May 25th) showed that the mortality rate of those infected in Omicron who were not vaccinated was 3.04%, while the mortality rate of those infected with three doses of vaccine dropped significantly to 0.04%.

Do the branches BA.2 and BA.5 all need their own vaccines?

According to WHO’s latest weekly report on epidemiological progress in COVID-19 (May 25th),Omicron BA.2 and its progeny pedigree (BA.2.X) have become the main popular variants in the world.At present, the relative proportions of BA.2.X, BA.4 and BA.5 are 94%, 0.8% and 1% respectively.

This shows that during the evolution of Omicron mutant, the branch BA.1 is disappearing. However, the reporter learned that at present, most vaccines against Omicron in China are designed and developed for BA.1.

Whether it is necessary to develop new vaccines for new branches, the industry generally judges from the perspective of vaccine protection: if the activity of neutralizing antibodies produced by the original vaccines against mutant strains is greatly reduced, it is necessary to develop new vaccines; If it still has a good neutralizing effect on the mutant, there is no need to develop a new vaccine.

Although Omicron strain mutates rapidly and different branches appear, butNew vaccines will not be introduced for each branch, and there is no need to do so.. Relevant experts reminded: "If you continue to monitor, you will find that many mutations will disappear soon."

Can vaccine update keep up with virus iteration?

In the technical route of vaccine development in COVID-19, the design cycle of mRNA vaccine is short. On the basis of a mature platform, the design can be completed within 7 days, and the preclinical trials including animal experiments can be completed in about one month.

Industry experts engaged in the research and development of mRNA vaccine said that for the variant branch, the mRNA vaccine does not need to obtain the strain, but only needs to optimize the vaccine sequence according to the variant sequence and test the expression efficiency, and then pre-clinical trials can be carried out. Covid-19 Omicron mutant mRNA vaccine, developed by Suzhou Aibo Bio, China, has been approved for clinical research in UAE.

In response to virus variation, the technical route of inactivated vaccine can also complete the preclinical study of new strains in a short time by establishing an emergency system. The reporter previously learned that it can be advanced to the clinical trial application stage about 2 months after obtaining the new strain.

Keep up with the variation, can COVID-19’s vaccine market learn from the "flu model"

In order to cope with the frequent mutation of viruses, there are precedents for vaccine updates to follow closely. For example, the influenza virus vaccine is recommended by WHO every year, and countries produce new influenza vaccines accordingly.

In order to keep up with the variation in Covid-19, can the "flu model" be used for reference in the marketing of vaccines in COVID-19?

“It is estimated that the future development of COVID-19 vaccine needs to adopt the influenza model.The authoritative experts mentioned above responded, but WHO is unable to recommend mainstream strains through monitoring now, because the pandemic is not over yet.

Another advantage of the "flu model" is that it greatly shortens the time to market for new vaccines. Because there is no need for re-approval, its batch issuance system can effectively shorten the period from vaccine development to marketing. Experts in the industry said that after polishing and construction, various technical routes and platforms have gradually matured, the research and development speed has been accelerated, and the production process has been stable.If the "flu model" can be adopted in the development and marketing of vaccines in COVID-19, the time to market for new vaccines will be greatly shortened.

WHO has revealed some unexpected phenomena in its weekly epidemiological report: available data show that BA.4, BA.5 and BA.2.12.1 spread faster in countries where BA.1 was once prevalent, but less in countries where BA.2 was prevalent; The vaccination degree of each country may have an impact on the popularity of the new branch of Omicron. Visible,Covid-19 mutation and vaccine immunogenicity are mutually causal and widely related, and updating the vaccine in time may have an impact on virus mutation.

1905 movie network news　Last weekend (01.18-01.20), the box office revenue in North America totaled $129 million, up 8.2% from the previous week. Monday is Martin Luther King Memorial Day, and we will continue to have a holiday. Among the new films on the list, M Knight Shamalan’s new film "Mr. Glass" earned $40.58 million in the first three days of the first weekend, which was close to $40.01 million in the first week of "Split" in 2017 and higher than $30.33 million in the first week of "Never Die" in 2000. Not surprised or pleased. The media mostly think that the content is too full and too anxious, but there is no emotional touch. They think that they are not attracted to fans of "The Dead Robber" or "Split" and become ungrateful at both ends. Another new film is a slightly niche animated film "Dragon Ball Super: brolly". The plot is based on the animated series "Dragon Ball". After telling the story of Wukong and brolly, it is biased towards fans. In the first week, it won 10.65 million US dollars in 1233 theaters in North America, but it attracted a limited audience and was not optimistic about its subsequent box office development.

"Mr. Glass" is too full of word of mouth, and the fans of "Dragon Ball Super: brolly" are serious

Recommended star rating of Mr. Glass: ★★★

"Dragon Ball Super: brolly" Recommended star rating: ★★★ (specific fan direction)

On the weekend of Martin Luther King’s Day, M Knight Shamalan’s new work "Mr. Glass" earned 40.58 million US dollars at the box office in North America from Friday to Sunday, which was close to 40.01 million US dollars in the first week of "Split" in 2017 and higher than 30.33 million US dollars in the first week of "Never Die" in 2000. In all the Martin Luther King Memorial Weekends, this box office ranked third, only behind the $41 million of "Sasaki Brothers" in 2014 and the $89 million of "American Sniper" in 2015. The production cost of Mr. Glass is $20 million, and the global box office has reached $90 million. These figures undoubtedly prove Shamalan’s ability to make money again. In fact, even in the low tide of Shamalan’s poor reputation, many of his films were very profitable. For example, in 2008, the production cost of "Death" was 48 million US dollars, and the final global box office was 163 million US dollars. In 2004, the production cost of "Mystery Village" was 60 million US dollars, and the final global box office was 256 million US dollars. What he really didn’t earn was only.

At present, the cinema score of Mr. Glass is B, IMDb score is 7.2, MTC score is 42, and the freshness of rotten tomatoes is 36%. "Hollywood Reporter" commented: "As the final part of the trilogy, this film is like a mixed bag, twisting all the previous narrative clues into one, but unfortunately trying too hard to tell the audience that Shamalan has a very special idea on the popular comic adaptation story, but the result is not shown." "Variety" said: "It’s still very happy to see Shamalan return, but" Mr. Glass "takes up more of our time, but it can’t create any touches, which makes people feel busy and dazzling, but there are few moving moments of emotional resonance." "International Screen" thinks: "Apart from McEvoy’s performance as a smoke bomb and Bruce Willis’s convincing charm, the whole film has actually not gone far in the concept of’ what happens when people become superheroes’." Due to the poor reputation, the follow-up box office track of Mr. Glass may be more similar to the Clover Files, which was opened on the weekend of Martin Luther King’s Day in 2008. The film earned $40 million in the first week and $80 million in the local box office.

Another noteworthy new film last weekend was the classic IP cartoon "Dragon Ball Super: brolly", which was only opened in 1,233 theaters in North America, aiming at clearly attracting a specific fan base, and won $10.65 million at the box office in three days in the first weekend. The story of "Dragon Ball Super: brolly" is a continuation of the upcoming TV animation "Dragon Ball", which tells the story between Saiyan brolly and Wukong. The film was nominated for the best cartoon in the 42nd Japanese Film Academy Award and was very popular among fans. At present, the media scores and fans’ scores of all platforms are very high, with IMDb score of 8.6, MTC score of 64 and the freshness of rotten tomatoes of 80%. The Los Angeles Times said: "brolly is ready to give Dragon Ball fans everything they want in a movie, and other viewers may feel lost in this world." Midwest Film Journal also thinks: "For the novice Dragon Ball, this film provides a dazzling animation time." There are also some media that don’t like it, such as "Movie Country", which means: "This is a meaningless garbage culture animation only for fans."

Old movies: "Neptune" local over 300 million "Upward" has a strong box office stamina.

Warner Bros.’ s superhero movie Neptune has entered its fifth week. After the weekend, the film’s box office outside North Captain America: Civil War has reached 759 million US dollars, surpassing’s 745 million US dollars, and the local box office has also exceeded 300 million US dollars. At present, the film’s global total box office is 1.063 billion US dollars, which is still 3 million US dollars short. Amber Heard’s Neptune can surpass Johnny Depp’s highest-grossing Pirates of the Caribbean: The Coffin. At the same time, Aquaman is also the movie with the strongest box office stamina after Teenage Mutant Ninja Turtles: The Age of Mutations in 2014. It is expected that Aquaman will have a good room for growth before The Lego Movie 2: The Second Part and Listen to Men’s Hearts come out on February 8.

In the following week, Upward Bound kept quite steady, with the box office of $15.6 million in three days over the weekend, which was only 23% lower than that in the first week. Earlier, many films in kevin hart fought bravely in Martin Luther King’s weekend, such as the above-mentioned Sasaki Brothers, Customized Best Man and Sasaki Brothers 2, and so on. This time, Upward Bound was opened in this schedule one week ahead of schedule. At present, the total box office of Upward is US$ 43.98 million. As long as it exceeds the US$ 48.7 million of Supersize Beauty last year, it will become the third domestic box office of STX Entertainment after bad mother and Christmas of Bad Mom. Sony’s Spider-Man: Into the Spider-Verse currently has a global box office of US$ 322 million, which has surpassed The LEGO Batman Movie’s US$ 311 million. The production cost of Spider-Man is US$ 90 million.

This week’s preview: Adventure "King Boy" Playing through the thriller "Quiet" arouses expectations.

This weekend (01.25-01.27), Fox’s youth movie "King Boy" and Matthew McConaughey and Anne Hathaway’s crime thriller "Quiet" will be widely opened in North America.

Fox’s "The King’s Boy" tells the story of a little fat boy, Alex, who accidentally pulls out and passes on the "sword in the stone" mentioned by H. As a destined little hero, he needs to unite his friends and the legendary wizard Merlin to fight against the eccentric witch Morgana. This is a story from modern times to legend, which will be opened in more than 3,400 theaters in North America this Friday. The crime thriller "Quiet" starring Matthew McConaughey and Anne Hathaway was postponed from last October to this week. It tells the story that Baker Dill, the captain of a fishing boat, received a request from his ex-wife Karen to help her kill her violent current husband. Karen’s appearance was forgotten in Jandyr, but in fact, the current situation is also city by the sea. The film will open in more than 2500 theaters this Friday.

On February 9th, Mary, the actor who made his eighth appearance on the stage of the Spring Festival Evening, came to the interview room. She said that every time she comes to the Spring Festival Gala, like the exam, she is particularly nervous and under great pressure. When she has good works, she will be more confident in acting, but this year’s time is relatively hasty.

Mary said that it is actually more difficult for an actress to act in comedy than an actor, because she is not willing to "sell" or "play", but rather wants to start from the characters, so whether it is the structure or the character of the role, it is still more challenging to act.

Talking about the upcoming film Article 20, Mary said that he didn’t expect to cooperate with director Zhang Yimou one day. From the day he joined the group, he felt that everything was like a dream. Mary also said that Zhang Yimou’s state of filming on the spot, his unique ideas, his requirements for actors and his control of all the plays made him feel that the director is the most attractive and soul person in the crew and the soul of a movie. "I think the director is like a god to me."

Recalling that in 2023, Mary admitted that he was a model worker. Last year, there were 3 or 4 films and played some very powerful female roles. The creative process was happy, but it was also very painful. The result was very satisfactory for himself. I hope I can give myself a holiday in the new year.

General Office of Guangdong Provincial People’s Government

February 8, 2017

North America is the largest film market in the world, and it is also the main battlefield to test the success or failure of a Hollywood film. Generally speaking, there are two institutions that regularly publish box office data of North American film market: the website Box Office Mojo mainly collects and counts the data reported by publishers themselves; Comscore, a media company specializing in collecting and analyzing all kinds of data, collects daily box office data from the cinema, which is also the main source of box office data for American media.

Traditionally, Comscore’s annual report will not be released until the first Tuesday of the new year, that is, January 2, 2024, local time in the United States, but it is said that the total box office in North America will basically fall between $9.03 billion and $9.05 billion in 2023. As for Box Office Mojo, because of the time difference, the North American box office figure in 2023 on this website is still at $8.905499 billion for the time being, but I believe it will be further updated in a few days.

"Baben Harmo"

Looking back on the key words of North American movies in 2023, the first one was "Baben Harmo": two commercial blockbusters with irrelevant contents and types collided head-on in the same schedule, and the result was not that they changed, but that they successfully ignited the audience’s enthusiasm together and became a phenomenal movie event in 2023. Barbie, produced by Warner Bros. Film Company, finally became the North American box office champion in 2023 with a score of $636 million, while Oppenheimer, produced by Universal Pictures, ranked fifth in the annual box office list in North America with $326 million.

The success of the two works has its own reasons, but to sum up, it is nothing more than abandoning the routine and highlighting the new ideas. Together with Universal Pictures’ Super Mario Bros. Movie, which ranked second in North America’s annual box office list with US$ 574 million, these three works can be said to have high original value.

Although Barbie comes from a world-famous popular toy, Super Mario Bros. Movie is based on a well-known video game of the same name, and the protagonist of Oppenheimer has already gone down in history because of the atomic bomb, they are not actually sequel to the movie or remakes of old movies, which can attract the audience to buy tickets and rely on real original stories and designs.

Stills of Super Mario Bros. Movie

In sharp contrast, in 2023, a lot of blockbusters failed at the box office, almost all sequels and series of works. In addition to the superhero movies that have completely tired the audience aesthetically, Raiders of the Lost Ark 5 and Mission Impossible 7 have also failed to achieve satisfactory box office results.

The total box office in North America in 2023 is definitely the highest in North America since the epidemic subverted the film industry, far better than the $7.46 billion in 2022 and $4.56 billion in 2021. However, such achievements have not returned to the level before the epidemic.

Historically, the box office in North America has steadily exceeded $10 billion every year since 2009, and since 2015, this figure has exceeded $11 billion every year. Before the epidemic, in 2019, although the box office performance of North American movies has been severely squeezed by the streaming media market, the box office of the whole year can still easily reach 11.4 billion US dollars.

On the surface, it seems that the main reason is that the number of films released by Hollywood studios is getting smaller and smaller every year: only 88 films were released on a large scale in 2023, while in 2019, the box office reached 10.5 billion US dollars, which was 108, a full 20 more. However, I really want to say, even if there are 20 more new films in 2023, will it be guaranteed that the box office will increase by 2 billion US dollars? Who can say that these 20 films will get an average of $100 million at the North American box office each?

Movies like Barbie and Oppenheimer can persuade people to pay for tickets because they can only appreciate the beauty of light and shadow when they are watched on the big screen, and the same is true for Taylor Swift: Time Tour Concert, which became a dark horse at the box office near the end of the year. In 2023, when the streaming media service is becoming more and more mature (and saturated), how many movies must be experienced in the cinema in the eyes of the audience? Below, we will look at it according to the winners and losers list of the five major Hollywood manufacturers.

Universal Pictures International

Wins: Super Mario Bros. Movie ($575 million), Oppenheimer ($326 million), Five Nights of the Teddy Bear ($137 million) and Megan ($95 million).

Negative: Speed and Fury 10 ($146 million), Renfield ($17 million), Demeter’s Last Voyage ($13 million).

According to film companies, Universal Pictures, which won $1.93 billion in 2023, topped the North American box office list. With the blockbuster films such as Super Mario Bros. Movie and Oppenheimer, Universal has occupied about 22% of the box office share in North America, slightly overwhelming Disney and winning the first prize since 2015.

In 2023, Universal occupied two seats in the top five most popular films in North America. In addition, the innovative thriller Megan, which cost only $12 million, also earned nearly $100 million at the box office, while Five Nights of the Teddy Bear turned the cost of $20 million into a box office of $137 million, making them the two most cost-effective movies in 2023.

Of course, Universal also made some mistakes in 2023, and the tenth The Fast and the Furious series was exhausted, but the production cost was getting higher and higher, reaching a shocking $340 million, which erased a lot of the annual bonus of Universal.

In 2024, Kung fu panda 4’s "Daddy Thief 4" and other works will be listed around the world, and there is still a chance to win the championship again.

Disney

Wins: Galaxy Guard 3 ($359 million), The Little Mermaid ($297 million), Crazy Element City ($154 million).

Negative: Captain Surprise 2 ($84 million), Indiana Jones 5 ($174 million), Star Wish ($61 million), Haunted House ($68 million).

2023 is Disney’s centenary birthday, which should have been a year worth celebrating. Various commemorative movies, books and activities were also arranged in advance. However, the overall commercial achievements released at the end of the year made 2023 a year when Mickey Mouse fell to the altar.

Since the annual box office accounted for 26% in 2016, Disney has become the sole overlord of Hollywood in the past few years by relying on its fist products such as Marvel Comics and Pixar; The peak appeared in 2019, accounting for 33.3% of the box office. Seven of the top ten films in the world were produced by Disney, and the box office of each film exceeded $1 billion, leaving the other Hollywood giants completely behind.

However, with the arrival of COVID-19, everything came to an abrupt end. Three years after the epidemic, Disney’s box office share was only 11%, 20% and 18% respectively. However, at that time, Disney’s box office declined because of the external factors of closed cinemas and filming stoppage, which can be said to be a crime of no war. By the end of the epidemic in 2023, Disney’s box office still accounts for only 16%, so you can only find the reason from yourself.

The most serious problem is naturally the continuous downturn of the Marvel movie universe. From "Ant Man 3" at the beginning of the year to "Captain Surprise 2" at the end of the year, all of them lost their eye-catching characteristics in the past, and the latter even became the worst box office in the history of Marvel Comics movies, which made Disney CEO Bob Iger admit that at the previous stage, they really made a big mistake of focusing only on quantity and ignoring quality. At the same time, it also reminds opponents once again that there has never been any panacea in Hollywood, and the tastes of the audience are changing rapidly. Sitting on one’s laurels and standing still is doomed to die.

"Galaxy Guard 3" poster

On the whole, among the top ten box offices in North America, Disney still has the illusion that "Guards of the Galaxy 3" ranks fourth, "The Little Mermaid" ranks sixth and "Ant Man 3" ranks eighth, and there is still the illusion that "the skinny camel is bigger than the horse". However, excluding the special circumstances of the epidemic for three years, this has become the first year since 2014 that Disney has not had any film with a global box office exceeding the $1 billion mark.

Of course, Disney’s advantage is that it has acquired a large number of high-quality assets through mergers in the past few years. After being acquired by Disney, 20th Century Fox, which originally belonged to the ranks of the six Hollywood manufacturers, was renamed 20th Century Pictures, and its box office was also included in the Disney Group’s evaluation. In 2023, they released three works, Cabinet Devil, Venetian fright night and AI Creator. Together with the release of Avatar 2 in early 2023, they earned about $400 million in North American box office. Including this part, Disney accounted for about 21% of the annual box office in North America, ranking second.

Warner Bros.

Wins: Barbie ($636 million), Nun 2 ($86 million), Meg 2 ($82 million), Wonka ($143 million).

Negative: The Flash ($108 million), The Blue Beetle ($72 million), Shazam 2 ($57 million), Aquaman 2 ($85 million).

With Barbie, the highest box office in North America in 2023 (the film also won the annual global box office champion with a box office score of $1.44 billion), Warner failed to become the North American box office champion in 2023, ranking third with only $1.4 billion and a share of about 15.24%. I am afraid that the reason can only be attributed to the poor box office performance of DC superheroes.

"Barbie" stills

In addition to Barbie, in 2023, Warner also tasted a lot of sweetness in the horror film Sister 2 and the family movie Wonka. However, they invested about $660 million in the production cost of the four DC films, The Flash, The Blue Beetle, Shazam 2 and Aquaman 2. As a result, the global box office revenue of the four films was less than that of the 2016 Batman v Superman: Dawn of Justice ($874 million).

In 2024, Warner will publish Dune 2, Godzilla vs. king kong 2, Clown 2 and other works, which hopefully will lead to a comeback.

Sony pictures

Wins: Spider-Man: The Vertical and Horizontal Universe (US$ 381 million) and The Wronger 3 (US$ 92 million).

Negative: Silly Money ($13 million) and Escape from Cretaceous ($32 million).

In 2020, when the world was in chaos, Sony Pictures once became the biggest winner in the North American film market, gaining more than 20% market share. After that, in 2021, they also continued to be in the forefront. However, in 2022, when everything is slightly back on track, Sony’s market share has retreated to the fifth place. In 2023, the situation is slightly better than that of Paramount, which is at the bottom. The annual box office of less than $1 billion accounts for about 11% of the market.

Stills of Spider-Man: The Vertical and Horizontal Universe

During the three years of the epidemic, Sony released about 16 or 17 works every year, and in 2023, it rose to 27, far more than any other Hollywood factory, and basically recovered to the level before the epidemic.

The animated film Spider-Man: The Vertical and Horizontal Universe, which was released in June, is a rare Marvel Comics movie that sold well at the box office in 2023. The global box office of "Grievance 3" also reached $190 million, almost the same as the first two films, showing the high popularity of Denzel Hayes Washington Jr.. As for "Napoleon" released at the end of the year, it is not a box office success in itself. After all, the production cost of the film is as high as 200 million US dollars. However, this huge sum of money basically comes from Apple with deep pockets, and Sony is only responsible for issuing, and the package will not be compensated.

In 2024, as usual, Sony will have a wave of new films such as Ghostbusters: The Frozen City, Garfield, Mrs. Spider: Super Awakening, Kraven the Hunter, Venom 3, etc., and the box office should make a breakthrough.

Paramount

Wins: Scream 6 ($108 million), Wang Wang Team 2 ($65 million), Teenage Ninja Turtles: Mutant Fight ($118 million).

Negative: Mission Impossible 7 ($172 million) and Dungeons and Dragons: The Glory of Grand Theft Auto ($93 million).

2023 is really a year to break the Hollywood convention. Not only has the invincible superhero movies been beaten, but even Tom Cruise, which has always been a box office guarantee, has experienced the existential crisis of Lian Po’s old age.

Before the release of "Mission Impossible 7", almost everyone expected that it would be Tom Cruise’s second successful summer file after "Top Gun 2". As a result, "Mission Impossible 7" failed to ignite the enthusiasm of North American people for watching movies on the first weekend, and was quickly defeated by Barbie and Oppenheimer. The most deadly thing is that the epidemic pushed the production cost of the film up to an astonishing $291 million, which caused it to bear an excessive burden before it was released.

Dungeons and Dragons: Glory of Grand Theft Auto poster

The box office failure of Dungeons and Dragons was also somewhat unexpected. After all, the film was adapted from a powerful game IP, and the audience’s reputation after the screening was very good, but perhaps because of the schedule, there was still a lack of enough audience to join in, which made this $150 million film unable to break even.

In the whole year, Paramount released a total of 10 films, with a box office of just over $800 million, accounting for about 9.6% of the total box office in North America, ranking fifth, far below the market share of 17.6% in 2022 with the blessing of Top Gun 2.

In 2024, Paramount will release some blockbuster new films, such as Gladiator 2, Transformers: The First Generation and Sonik the Hedgehog 3, which is expected to turn the tide.

Taylor Swift: Time Tour Concert Poster

In addition to the above-mentioned five Hollywood giants, Lionsgate Pictures, which took 6.55% of the market share, ranked sixth in the annual box office in North America. They released 12 films in the whole year, and "Fast Chasing 4" ranked ninth in the annual single box office in North America with $187 million. Further back, the independent film "Voice of Freedom", which is not unusual in shooting, distribution and publicity, won $184 million at the box office, which just squeezed into the tenth place in the annual single-chip box office list in North America.

Taylor Swift: Time Tour Concert, with the same maverick distribution model, earned $179 million at the box office, ranking 11th in the annual single-chip box office list in North America. Independent films like this broke into the top of the annual box office list for more than ten years, which seems to reflect the coming of the unprecedented changes in Hollywood in N years.

　　Our reporter Gu Mengxuan Xia Xin reports from Guangzhou and Beijing.　

　　Recently, the international gold price hit a record high and was quickly sold off, causing a sharp drop. The price of gold denominated in RMB has also fluctuated greatly, which has aroused widespread concern in the market.　

　　On December 4th, the price of gold futures in new york market once rushed to the $2,150 mark per ounce, with an intraday increase of over 3%, setting a record high. Subsequently, the price of gold quickly fell back, and as of the 7 th, the cumulative correction per ounce exceeded $100.　

　　Affected by this, the gold Au99.99 listed on the Shanghai Gold Exchange fell back after it surged to 487 yuan per gram on the 4th, and the retail price of some domestic brands of gold jewelry stood at the high level of 630 yuan per gram and then fell back to about 615 yuan per gram on the 7th.　

　　According to Wind data, on December 15th, the New York Mercantile Exchange gold futures price was reported at 2018.3 USD/oz; As of press time, the gold Au99.99 listed on the Shanghai Gold Exchange is 472.99 yuan per gram.　

　　Welcome to a loose inflection point　

　　Regarding the correction of gold price, Wang Xiang, fund manager of Bosera Fund Index and Quantitative Investment Department, pointed out that the Fed’s interest rate hike cycle tends to end, which will usher in a loose turning point. Gold benefits from the downward logic of liquidity easing and real interest rate. Historically, similar policy nodes have strong price support power. However, there is a profit-taking impulse near the historical high point, and the net long position of short-term COMEX futures fund is too fast, so there is a need for adjustment.　

　　At 3: 00 am on December 14th, Beijing time, the Federal Reserve issued the statement of the FOMC meeting in December 2023 (the Federal Reserve’s meeting on interest rates), and once again announced the suspension of interest rate hikes.　

　　According to the data provided by Bosera Fund, inflation expectations in the United States have dropped significantly. In December, the consumer confidence index of the University of Michigan rose to 69.4, with an expectation of 62. The inflation expectation dropped significantly, with the one-year inflation expectation dropping from 4.5% to 3.1% and the five-to ten-year inflation expectation dropping from 3.2% to 2.8%. "This combination is not good for precious metals." Wang Xiang said.　

　　As for the rise in the price of gold in the early stage, Bi Mengyu, an investment researcher at Geshang Caifu Jinyu, pointed out that gold, as a non-interest-bearing physical asset, often ushered in rising opportunities when other assets had poor returns.　

　　First of all, from an economic point of view, the global economy is currently in recession. In view of the worries about the economic downturn and the stock market decline, driven by risk aversion, investors are more willing to buy gold to avoid risks, leading to the rise of gold prices. In November, the global manufacturing PMI (Purchasing Managers Index) was 49.3, the US manufacturing PMI was 46.7, and the Eurozone manufacturing PMI was 44.3, all of which were below threshold, reflecting the overall global economic downturn.　

　　Secondly, last week, the ADP data in the United States (an economic indicator commonly used to measure the job market) failed to meet expectations. The market speculated that the Federal Reserve would not raise interest rates in December, that is, the nominal interest rate showed a downward trend with a high probability, which made the price of gold rise again.　

　　Finally, global central banks continue to purchase gold, and the demand for gold purchase by global central banks will remain strong in 2023, which supports the upward trend of the overall price of gold.　

　　"The adjustment of gold this week was mainly due to the rising interest rate of the US dollar index and US debt after the US non-farm payrolls data exceeded expectations, and coupled with the’ hawkish’ signal released by the Federal Reserve Chairman, the price of gold fluctuated downward." Bi Mengyu said.　

　　The annualized compound yield of gold is 7%　

　　The reporter noted that in August this year, the trend of domestic and international gold prices deviated greatly. In recent months, has the excessive price difference between the internal and external markets of gold prices been corrected?　

　　Wang Xiang pointed out that in September this year, the price difference between domestic and foreign countries was the highest, 30 yuan+/gram, and at present, the price difference has largely converged to 7 yuan/gram, but it is still far from the historical 95% confidence fluctuation range of 1.2~1.8 yuan/gram. In the process of convergence, the performance of domestic gold price will be worse than that of dollar gold.　

　　Bi Mengxuan pointed out that the international gold price and the domestic gold price are basically in a positive correlation, but due to the influence of pricing system, rate and time lag, they may deviate in the short term, and the domestic gold price fluctuation is often lagging behind. After several months of adjustment, the international and domestic gold prices have basically converged.　

　　Central banks around the world have also shown sustained enthusiasm for buying gold. According to the data of the World Gold Council, in 2023, the global central bank’s demand for gold purchases remained strong, reaching 387 tons in the first half of the year, a record high in the same period; In the first three quarters, the amount of gold purchased reached a record 800 tons, a year-on-year increase of 14%. At the same time, the data released by the State Administration of Foreign Exchange showed that at the end of November, the gold of the Bank of China had increased for the 13th consecutive month.　

　　In this regard, Bi Mengyu pointed out that the central bank’s allocation of gold mainly considers security, liquidity and return. First of all, gold is regarded as a safe asset and a value-preserving asset by the central bank, because it is more stable in the face of credit risks than other assets such as national debt; Secondly, gold has strong liquidity, and the central bank can quickly enter the market without distorting the price; Finally, although the return is not the main motivation for the central bank to buy gold, the annualized compound rate of return of gold has been around 7% in the past few decades, providing investors with relatively considerable returns.　

　　"The proportion of gold in China’s foreign exchange reserves is still low. Although it has been continuously increased, the current proportion is still less than 6%, which is still far from the proportion of more than 40% in European and American countries." Wang Xiang said that increasing the proportion of gold in foreign exchange reserves will help to diversify the reserve structure and maintain the stability of local currency and asset prices during the contraction cycle of the US dollar.　

　　Rational investment by investors　

　　Regarding the future market of gold assets, Nuoan Fund pointed out that due to the issuance of bonds by the US Treasury, the reduction of US debt holdings by the Federal Reserve and the current strong economic expectations, it is expected that the long-term yield of US debt will remain high, and short-term gold will still be suppressed by interest rates and the US dollar index. However, we expect that the signs of economic slowdown in the United States may be more obvious in the first half of 2024, and high interest rates and recent geopolitical risks may increase the volatility of financial markets compared with the previous period. The logic of gold investment gradually shifts from short-term safe-haven demand to medium-and long-term Fed interest rate cuts. Recently, the market expects the Fed to cut interest rates, which has significantly boosted the price of gold, or it is expected to change more by pricing. It is suggested that investors should actively pay attention to the trend of gold price and consider the proportion of gold allocation to grasp the investment opportunity of gold.　

　　Wang Xiang said that whether inflation converges smoothly, leading European and American monetary policies to shift to liquidity logic, or inflation rises again due to unexpected events, taking stagflation logic, different macro paths are beneficial to the gold margin, making it still one of the assets with high certainty, and the only difference is the difference in odds. Next year is an election year for many economies, and the intensity of geo-game may remain at a high level, which is also conducive to the rise of the price center. The upward target of USD gold is USD 2,200 ~ 2,400, which is about 515~550 yuan/g in China.　

　　"It is normal for the regional fluctuation of gold prices to increase near historical highs. Investors should neither be overly enthusiastic in the overbought state of the market, nor completely lose confidence after their breakthrough failure." Wang Xiang pointed out that in the medium and long term, the easing of the Federal Reserve and the weakening of the US dollar will remain a high probability path next year. With many economies entering the election year, the intensity of geo-game will remain at a high level. After the short-term selling sentiment is released, gold will return to its long-term upward path again.

　　CCTV News recently reported on the safety investigation of self-heating hot pot.

　　You don’t need fire or electricity, just add a bottle of water, and you can enjoy the hot pot … … Nowadays, the so-called "lazy people cook their own hot pot" has quietly become popular, and some brands have also introduced self-heating foods such as rice, noodles and vermicelli. However, in the investigation, the reporter found that although the self-heating convenient hot pot is delicious and fast, there are certain safety hazards. The heating package of self-heating food is flammable and explosive, so consumers should be very careful when using it, and it is not allowed to take it by train or plane.

　　What is a self-heating hotpot?

　　Self-heating hot pot does not need fire or plug in electricity, and it is mainly composed of ingredients, an ingredient pot, a pot cover, an outer pot and a heating bag. The heating principle is to use the substance in the heating bag to contact with water to release heat, so that the temperature of the food in the upper food pot increases after absorbing heat. Besides self-heating chafing dish, it is also called micro chafing dish, clear boiled chafing dish and self-cooking chafing dish.

　　This product, which first appeared in Wechat business’s circle of friends, attracted more and more catering and food companies to join. From making hot pot bottom materials to chain hot pot restaurants, many companies have started self-heating small hot pot business. Even a good shop that makes snacks sells self-heating hot pot in its own Tmall flagship store. Now go to e-commerce platforms such as Tmall and JD.COM to search for "self-heating hot pot", and at least nearly 30 brands will appear.

　　Eat a hot pot and call the police!

　　However, there is no small safety risk in this convenient hot food. The reporter noticed that there are many reports on the Internet that the alarm will give an alarm when the self-heating hot pot is used, and consumers have sent the video that triggered the continuous alarm of the gas alarm when using the self-heating hot pot to the short video platform.

　　Consumer Xiao Chen has been afraid to eat self-heating hot pot at home since it caused the gas alarm to call the police. According to reports, she was operating in the kitchen according to the instructions. After the lid began to steam, she planned to go back to the house for a while, but before she left the kitchen, the gas alarm suddenly rang.

　　"At that time, I was shocked. I was afraid of gas leakage and specially called the gas company. The other party said that the gas did not leak after the door-to-door inspection." The inspectors said that it may be caused by the self-heating chafing dish, because the gas alarm will only give an alarm when it detects that carbon monoxide exceeds the standard, which may be caused by the gas released when the self-heating chafing dish is heated.

　　In addition, consumer Xiao Li told reporters that once he ate self-heating rice on the glass coffee table at home, the vent hole on the lid of the box just burst, and he heard a bang, and the corner of the glass coffee table burst, causing the rice to spill all over the floor.

　　The reporter bought a box of self-heating hot pot at random. After unpacking, first put the hot pot bottom and all the ingredients into the lunch box and add cold water. Then tear off the outer bag of the heating package and put it in the bottom box, and add cold water without heating the package. Place the food box on the heating bag, open the vent hole on the closed cover and cover the hot pot tightly. After a few seconds, steam will be ejected from the vent hole. After a few minutes, the sound of boiling water will be heard in the box, and the box will expand and deform when heated, and the high temperature can be felt near the lunch box. After more than 10 minutes, the box gave out a bang, and then the gas alarm at the reporter’s home rang. Turn off the gas alarm and wait for a few minutes, open the airtight cover, and high-temperature steam will blow on my face. In the process of eating, the self-heating hot pot has always maintained a high temperature. After eating for an hour, the outside of the lunch box still feels hot.

　　The manufacturer said this.

　　Why does the alarm continue to alarm?

　　So, what is the reason that causes the gas alarm to alarm continuously? The reporter dialed the telephone number of the manufacturer of the heating package. "When the heating package heats up, it will produce a small amount of hydrogen, because hydrogen will cause the smoke sensor to alarm." The person in charge of a heating package manufacturer said. Hydrogen is a combustible and reducing gas. Pure hydrogen burns quietly in the air, while impure hydrogen may explode when it burns.

　　Is it dangerous to generate hydrogen in the heating package?

　　However, in view of the hydrogen generated during the reaction of the heating package, the personnel of the manufacturer claimed to the reporter that "there is absolutely no safety hazard".

　　The person in charge of a heating package manufacturer told the reporter: "It doesn’t matter. If that thing is dangerous, it can’t be so hot in the market. Don’t think it’s so dangerous, it’s not so dangerous, and big companies are doing it."

　　safety test

　　1 In a confined space, the heating package has the risk of deflagration.

　　The manufacturer of the heating package said that there was absolutely no potential safety hazard. However, reports about the alarm of the self-heating food appeared from time to time. Then, is there a safety hazard after the heating package reacts with water?

　　Not long ago, the Shanghai Consumer Protection Committee informed about the testing of 20 self-heating instant hot pot products. The test items include the inspection of appearance and packaging label, the surface temperature of the pot, the gas released by the heating package when it meets water, the secondary water addition reaction of the heating package, the composition and content of the heating package and other indicators. The test results show that all the tested heating packages belong to "substances or mixtures that emit flammable gases when in contact with water".

　　Shang Zhaocong, executive deputy director of the National Chemical Product Safety Quality Inspection Center, told the reporter: "We have done a lot of experiments, and basically each heating package can generate about 40 liters of hydrogen. The combustion limit of hydrogen in air is 4% to 75.6%. Of course, there are other closed or semi-closed conditions, such as inside the car, which will have similar risks. "

　　You should also be careful when eating hot pot together on the tourist bus.

　　Not only the self-heating food may bring the risk of deflagration when it is used in a closed space, but also it has great safety hazards when it is used intensively in some public places.

　　Xiao Qiuping, assistant director of the National Chemical Products Safety Quality Inspection Center, said: "For example, many tourists don’t know that hydrogen will be generated during the driving of tourist buses and long-distance buses. The large-scale use of self-heating hot pot may lead to the accumulation of hydrogen in vehicles, especially in summer, when the air conditioner is turned on, and the whole compartment is in a closed environment. In this case, if the lower explosion limit concentration is reached and a little fire source is encountered, a lighter is not needed.

　　3 After using the discarded heating package, there are still potential safety hazards.

　　Experts also told reporters that not only the self-heating products may bring the risk of deflagration after reaching the deflagration limit value of hydrogen in the use process, but also there are safety hazards after using the discarded heating packages.

　　In this experiment, the Shanghai Consumer Protection Committee also submerged 20 sample heating packages in water again. The results show that there are 14 samples of heating packs with different degrees of continuous deflation. The reaction duration is more than 3 minutes, and the longest is 8 minutes.

　　If such a heating package is discarded and meets water in a closed space such as a garbage can, and a little fire source is added, it may burn.

　　Safety warning to be standardized, safety standards to be issued.

　　In terms of product standards, there are currently no national and industrial standards related to self-heating instant hot pot products and heating packages in China. In fact, this unpredictable but possible security risk needs to be clearly reminded before users use it. However, the reporter found that at present, no self-heating product on the market has made a clear warning against these problems.

　　Cai En, director of the Consumer Guidance Department of the Shanghai Consumer Rights Protection Committee, said: "The manufacturer of heating packs should first make further tests and analysis on the components and related proportions of its heating packs, including the weight, to ensure that this heating pack can fully respond and ensure the safety of consumers when using it."

　　In this test, 18 samples of heating packages were marked with main components and corresponding enterprise standard codes. According to the marked main components, it can be divided into two groups: group ⅰ is calcium oxide, aluminum particles and sodium bicarbonate; Group II is calcium oxide, aluminum powder, sodium carbonate and sodium hydroxide. The heating packages of the other two self-heating instant hot pot samples were not marked with ingredients and enterprise standard codes.

　　According to the Catalogue of Hazardous Chemicals (2015 Edition) issued by state administration of work safety and other ten ministries and commissions, "aluminum powder" belongs to hazardous chemicals. In the list of dangerous goods in the United Nations Model Regulations on the Transport of Dangerous Goods, "uncoated" aluminum powder belongs to the listed 4.3 substances that release flammable gases when meeting water; Sodium hydroxide belongs to the listed class 8 corrosive products. When transported by air, calcium oxide belongs to the eighth corrosion product listed in the list. The heating package belongs to the substances listed in the list that release flammable gas when it meets water.

　　According to the classification standard of the United Nations "Recommendations on the Transport of Dangerous Goods Model Regulations", the self-heating instant chafing dish products are dangerous goods in transportation, because of the danger of releasing flammable gas when encountering water.

　　Therefore, China’s civil aviation system has completely banned the carrying of self-heating products on the plane. The regulations on railway safety management issued by Guangxi also clearly stipulate that it is forbidden to use self-heating food on bullet trains.

　　Use reminder

　　Shanghai Consumer Protection Committee reminds consumers:

　　● Read the instructions of the product before use, and operate in strict accordance with the prompts, especially not in closed and narrow environments such as cars, avoiding naked flames, and minors can use it under the guidance of adults.

　　● When using, please pay attention to placing the product on the anti-scalding table, and avoid touching the outer pot to avoid scalding.

　　● After use, the instant chafing dish garbage should avoid massive accumulation or direct contact with water, and be classified according to the regulations of Shanghai Municipal Domestic Waste Management, and the used heating package should be classified and disposed according to harmful waste.

　　Self-heating food raw materials have the problem of nutrient loss.

　　Chen Rong, president of the Nutritionist Association of Heilongjiang Province and a national first-class nutritionist, said that the nutritional value of vegetable raw materials in self-heated food could not be compared with that of fresh vegetables.

　　Comprehensive CCTV, interface news, life newspaper, etc.
