The topic of ＂super moon＂ has been searched frequently： how to form it？ How to observe？

　　Beijing, March 12 (Reporter Shangguan Yun) A bright moon often entrusts people with good wishes and thoughts. Recently, topics related to the "Super Moon" have been on the hot search for many times, and astronomy enthusiasts have chosen the right time and place to observe and feast their eyes.

　　In fact, the "super moon" is an astronomical phenomenon that everyone has paid more attention to in recent years. So, what is a "super moon"? When does it usually appear? How can people observe?

　　Conditions for the formation of "super moon"

　　To form a "super moon", two basic conditions need to be met, one is "nearest" and the other is "roundest".

　　"The orbit of the moon around the earth is elliptical, with the closest perigee and the farthest apogee." Yuan Fengfang, director of popular science at Xinglong Observation Base of National Astronomical Observatory of Chinese Academy of Sciences, explained.

　　She said that "super moon" means that the moon is at the perigee when it is at the full moon. At this time, when the moon comes to perigee, it looks bigger than usual because it is close to the earth.

　　"February 19, 2019 is the Lantern Festival in China, which happens to be ‘ Super moon ’ 。” Yuan Fengfang said, "The super full moon meets with our traditional festivals, which is more ornamental and attracts public attention."

　　How to watch "Super Moon"?

　　To watch the super moon, strictly speaking, you can choose to observe it when the moon-earth-sun is closest to a straight line in sequence. To put it simply, on the night when the "super moon" appeared, it can be observed anywhere as long as it is sunny or in partly cloudy.

　　Yuan Fengfang introduced a set of data. At 10: 35 am on April 8, Beijing time, the moon, the earth and the sun were almost in a straight line, and the moon was the most round at this time; At 2: 08 am on April 8, Beijing time, the moon reached perigee.

　　She said that it is suitable for observation from the evening of April 7 to the morning of the 8 th. You can shoot a moon at 2: 08 am on April 8 and before sunrise.

　　"In fact, we can appreciate it with our eyes ‘ Super moon ’ You can also use ordinary binoculars or monoculars, or even SLR and telephoto lenses. " Yuan Fengfang explained that "super moon" is a very common astronomical phenomenon. "We can see the full moon every month, can’t we?"

　　Appear no more than 4 times a year.

　　Earlier, some media reported that astronomical experts said that the "super moon" mostly happened on the 15th and 16th lunar months, and it will be staged four times in the Year of the Rat in the lunar calendar, and the time will be on February 9th, March 10th, April 8th and May 7th respectively.

　　“‘ Super moon ’ In fact, it is only a very common phenomenon. The period between the moon’s arrival at perigee takes 27.55 days, and the period between two full moons is the full moon, which takes 29.27-29.83 days. " Yuan Fengfang said.

　　There is a small time difference between the above two periods. Yuan Fengfang said that it is precisely because of the difference in the length of the cycle that there are no more than four "super moons" every year.

　　Interestingly, Yuan Fengfang mentioned that the perigee of the moon on April 8 was about 500 kilometers closer to the earth than the perigee on March 10. Therefore, the "super moon" on April 8 will be a little bigger (about 0.1%), but it is difficult for the naked eye to see the difference in size.

　　Interesting "Minimum Moon"

　　It is worth noting that there are not only "Super Moon" but also "Minimum Moon", and some netizens jokingly call it "Super Little Moon".

　　The so-called "minimum moon", that is to say, when the moon is full moon, it just runs near the apogee.

　　"The only time in 2020 ‘ The smallest moon ’ , on October 31. " Yuan Fengfang suggested that interested people can take pictures of the "Super Moon" and the "Minimum Moon" in the same place and use the same set of shooting equipment, and then make a comparison. This is an astronomical observation that the general public can do. (End)

The woman pays the deposit to pick up the car, and the price is increased. 4S shop： The sales agreement is invalid without signing.

　　On December 30, 2019, Ms. Cao of Wuhan reported to the complaint platform of the quality report that she bought a Cadillac XT5 sedan during the Wuhan Auto Show in November, signed a car booking agreement on the spot and paid a deposit of 10,000 yuan; However, when he was told to pick up the car at the end of December, he was told by the 4S shop that he needed to temporarily increase the price by 6,500 yuan, otherwise he would not leave the car.

　　On January 2, 2020, the customer service staff of Wuhan Hengxin Xingkai Automobile Sales & Service Co., Ltd., which belongs to the 4S shop involved, told The Paper that the car booking price was supported by the manufacturer during the auto show, but because the customer picked up the car after the time supported by the auto show price, he could only raise the price or refund the deposit of 10,000 yuan. In addition, the vehicle booking agreement signed at the time of car booking is invalid because it is not signed by the sales consultant.

　　Xing Xin, a partner of Hunan Jinzhou Law Firm, believes that the 4S shop asked for a fare increase when communicating with Ms. Cao to pick up the car, which shows that the validity of the agreement has not been denied. Ms. Cao has the right to protect her rights and interests by bringing a lawsuit to the court.

　　Ms. Cao introduced that in November 2019, at the booth of Cadillac at Wuhan International Expo Center Auto Show, she ordered a black Cadillac XT5 sedan on the spot. After many times of communication with the sales, the price was 275,700 yuan. On the same day, she signed a car booking agreement and paid a car purchase deposit of 10,000 yuan. It was agreed with the sales that the date of picking up the car was "before New Year’s Day".

　　After booking the car, Ms. Cao repeatedly asked about the time of picking up the car, and was told by the 4S shop that the booked car had not arrived at the store. On December 27th, the sales staff of 4S shop contacted Ms. Cao, saying that the car could be picked up, but it needed to increase the price by 6,500 yuan, otherwise the car booking agreement signed during the auto show would be invalid.

　　Ms. Cao said that at the auto show, the salesperson told her that there was a special preferential price during the auto show, and she could not get this discount after the auto show. She only paid the deposit and signed a car booking agreement during the auto show.

　　As can be seen from the car booking agreement provided by Ms. Cao, the agreement clearly indicates that the car price of the reserved car is 275,700 yuan, the delivery time is "the car arrives at the store" and Party B pays the full amount of the car, but it does not mention the specific time of picking up the car and the effective period of the car price.

　　It is stated in the agreement that the agreement can take effect only after Party A (4S shop) seals it and Party B signs it, but there is no company seal or sales consultant signature on the agreement.

　　On January 2, The Paper called Wuhan Hengxin Xingkai Automobile Sales & Service Co., Ltd., which belongs to the 4S shop involved. The customer service staff of the company said that in November, the customer signed an order for car booking at the auto show, and the price at that time was indeed supported by the manufacturer’s price. However, because the customer picked up the car after the auto show price support time, he could only pick up the car at a higher price.

　　"If the customer picks up the car in November, we can still follow the agreed price, but now the price has gone up, from 275,700 to 282,700, and there is nothing we can do." The customer service said that the vehicle booking agreement needs to be signed by both the customer and the sales consultant, but Ms. Cao’s vehicle booking agreement is only signed by the customer and not signed by the sales consultant, which is an invalid agreement.

　　In this regard, Ms. Cao said that the current status of the electronic agreement is indeed that the sales are pending. "But when booking a car, the agreement is operated by 4S shop sales on the APP, and the content is also written by them. At that time, I didn’t think so much. I signed it first, but I didn’t know it was so dishonest."

　　On the afternoon of January 2, after many consultations, the customer service staff of Wuhan Hengxin Xingkai Automobile Sales & Service Co., Ltd. told The Paper that two solutions have been proposed at present: the first one is that the customer raises the price by 6,500 yuan to pick up the car; Second, if the customer is unwilling to add money, he can refund the deposit of 10 thousand yuan.

　　In view of the above, Xing Xin, a partner of Hunan Jinzhou Law Firm, believes that the car booking agreement belongs to an electronic contract, and the salesperson, as an employee of the 4S shop, has acted as a duty behavior since the salesperson sent it to Ms. Cao, which can already be regarded as an invitation issued by the 4S shop. After Ms. Cao signed the agreement, it was regarded as a promise, and at the same time, Ms. Cao paid the deposit, and the agreement was established and came into effect. "The 4S shop asked for a fare increase when communicating with Ms. Cao to pick up the car, indicating that it did not deny the validity of the agreement, and it was also regarded as a de facto recognition of the validity of the agreement."

　　Therefore, Xing Xin believes that the agreement does not take Ms. Cao’s car pick-up in November as a restrictive condition for the preferential car payment, and increases the price when picking up the car. Ms. Cao has the right to ask the 4S shop to continue to perform the agreement by bringing a lawsuit to the court.

Chen Kexin’s mobile phone shooting ＂Three Minutes＂ touched people’s hearts.

　　These days, a short film "Three Minutes" has exploded the circle of friends, which tells an unusual reunion in Spring Festival travel rush. The story is very simple. The mother in the film is a train attendant on the "Nanning to Harbin" line. It is the busiest time to work overtime during the Spring Festival, and her son Ding Ding, who is about to go to elementary school, misses his mother, so he asks his aunt to take him to the train station next to his home and meet him while his mother’s train stops on the platform for 3 minutes. This Spring Festival travel rush-themed short film was shot by Hong Kong director Chen Kexin, and the content of the short film was based on a true story. After the short film was launched, it was played more than 13 million times on Youku in one day. Enthusiastic netizens also found the prototype of the story.

　　The story is based on true events.

　　The joy in the compartment or the joy of meeting relatives on the platform are the most familiar memories of the Spring Festival. This can’t help but remind people of the mainland realistic film "Dear" filmed by Chen Kexin a few years ago. The strong local flavor and sense of reality in the film will also surprise people that the film was produced by a Hong Kong director.

　　Outstanding storytelling ability, keen perception of details, concern for reality and strong humanistic feelings are Chen Kexin’s consistent styles. Chen Kexin said that although he has no experience in Spring Festival travel rush, the Spring Festival and reunion are the themes he has been paying attention to for many years. "I can fully imagine the joy and happiness when Spring Festival travel rush comes home." When "Three Minutes" was filmed in Chongqing, Chen Kexin saw the crowds surging on the platform. Although there were all extras in front of him, he was still infected by this feeling of returning home. When the audition actors sang the song of returning home for the New Year, he said that he was also moved to tears.

　　The short film touches the audience, not only because the flight attendants are busy on the train every Spring Festival, but also because the most critical structural design of the plot is that after the train stops at the platform, the mother and son meet for only 3 minutes. Three minutes, the sense of time limit brought by this reunion is the tension of the plot. The short film specially emphasizes this sense of time with the creative idea of 3-minute countdown. In the film, the countdown number is displayed at the top of the screen, which reminds the audience that the separation time between mother and son is approaching from the time the train enters the station. When entering the station, my mother saw her son on the platform through the window, but when the door opened, she had to help the passengers get on and off first, so she couldn’t find her son at the first time. Because there were too many people on the platform, my son couldn’t find his mother at the first time. When the child found his mother through the crowd on the platform, the time of 3 minutes has become 2 minutes. When the mother and son met and hugged, the mother waited for her son to speak with eager eyes. An interesting scene happened. After a moment of silence, the son began to recite the multiplication formula loudly. It turned out that my mother had joked with her son who was about to go to elementary school, "If you can’t recite the multiplication table, you can’t go to school, let alone see your mother." On the platform, my son didn’t recite the formula fluently, and at this time, the countdown on the screen was changing rapidly. The mother didn’t know what to do, and she couldn’t bear to interrupt her son. The tense countdown contrasted with the child’s stuttering recitation, which touched the audience’s mood. When my son recited the multiplication formula, the train started. The brief reunion of mother and son left the audience with endless aftertaste without a few words of dialogue.

　　During the Spring Festival travel rush season, many people are close to their relatives because of their work, but they can’t stay. The short film "Three Minutes" is based on such a real thing. After the short film was screened, some enthusiastic people found the prototype of the story in the film. She is Liu Zhong, the conductor of the Shenzhen-Urumqi team of Guangzhou Bureau Group Co., Ltd. of China Railway. On January 24, 2017, the media reported the story that Liu Zhong met his son Chen Hongjin (nicknamed Ding Ding) during the four minutes when the train stopped at Hengyang Station after passing through his hometown in Hunan. At the premiere of Three Minutes, director Chen Kexin said that when he first saw the story, he decided to shoot it. In the short film, Tintin recited "99 Multiplication Table" to his mother. In reality, Tintin showed his mother "ma ma wo ai ni" written in pinyin.

　　For Chinese people, Spring Festival travel rush is a journey to return home or find their own roots. The director Chen Kexin from Hong Kong has never experienced Spring Festival travel rush, but he has touched countless audiences with simple pictures, regardless of Spring Festival travel rush in the short film.

　　Mobile phone shooting movies has its own advantages.

　　This 7-minute short film continues Chen Kexin’s narrative style of paying attention to reality and storytelling. What’s more special is that it is a short film shot with a mobile phone all the time, and it is also the first time that Chen Kexin was invited by Apple to shoot a short film with a mobile phone. When sharing his own shooting experience, Chen Kexin said that "Three Minutes" gives the audience some perspectives that traditional films can’t touch. The current mobile phone photography technology has reached a very high level, which can not only record people’s daily life, but also serve as a lens supplement to traditional film photography. In "Three Minutes" shot by mobile phone, the vision of the characters in the picture is more realistic. In the short film, the subjective shot of the little boy crossing the platform to find his mother is completed by putting his hand in front of the little actor, which shows the rhythm and height of the movement, which is closer to a child’s perspective.

　　Nowadays, more and more young people without professional training are shooting their own works with their mobile phones. As a daily tool, mobile phones are far beyond the reach of cameras in portability. When shooting in a narrow indoor space, in fact, a considerable space is needed behind the camera to set up the machine, and with such a small device as a mobile phone, you can freely take pictures even in a narrow and crowded train compartment. For the advantages of mobile phone shooting, Chen Kexin greatly praised: "Compared with bulky cameras, mobile phone shooting can try the effect of dynamic camera movement, and it also brings many unique and different shooting angles. For example, you can put your hand frame very close to the actor to capture the true feelings of the characters without making the actors feel disturbed, which is an advantage that traditional large cameras do not have when shooting at close range. "

　　After "Three Minutes" was broadcast online, many netizens were surprised that the picture texture taken by the mobile phone could actually achieve the effect of big screen broadcast, but some knowledgeable netizens reminded: "Don’t think that there is only one iPhoneX between you and Chen Kexin’s" Three Minutes ",but it is actually several times more expensive than the mobile phone. Stabilizer, adapter, lens, drone and palm photographer & HELIP; …” In Chen Kexin’s view, all auxiliary equipment is just a tool to help the director establish an emotional link with the audience. The most important thing in filming is not technology, but creativity. Technology is just a tool, and more and more convenient and practical tools provide the possibility for realizing creativity. The short film "Three Minutes" not only impressed the audience, but also clearly conveyed that the future may enter an era in which everyone is a photographer. The development of science and technology is giving more ordinary people and video lovers the opportunity to complete their dreams about images.
