Plot introduction

In Longmen Village, an anti-Japanese base area in North China, Zhao and his son lived. His father, Lao Zhao, is the squadron leader of the militia, and his son, Hai Wa, aged 12, is the head of the Children's League. One day, my father got the news that the devils were going into the mountains to grab food, so he asked Hai Wa to send a letter to the Eighth Route Army about attacking enemy turrets.

Under the cover of herding sheep, Hai Wa took the letter with him. I didn't expect to meet a devil on the way. Hai Wa used his quick wits to hide the letter under the big tail of a sheep. The devils robbed Hai Wa's sheep and forced him to lead the way to Longmen Village.

At night, while the enemy was sleeping, Hai Wa took the letter and ran away. On the way, the letter was once recovered, but Hai Wa was caught by the enemy again. Resourceful and brave, Hai Wa deliberately led the enemy astray. At this time, the enemy knew the trick and pulled out a gun to hurt Hai Wa's hand. At the critical moment, the Eighth Route Army came to the rescue and wiped out the enemy soldiers. Hai Wa fainted after completing the delivery task. According to the information provided by Ji Maoxin, the Eighth Route Army blew up the enemy's turret and captured the commander's cat's eye alive.

Who was in the warm pit when Hai Wa woke up? There are sweets and biscuits on it. Hai Wa asked Zhang Lianchang if he had surrendered his gun. There are many guns piled up in the corner. So Hai Wa told the company commander that he wanted a gun.

Film evaluation

New China Children's Movie Classic!

The film "Chicken Hair Letter" was adapted by the famous film artist Zhang Junxiang from Huashan's novel of the same name. It is the first children's film in New China that positively reflects the struggle of China children against the enemy in War of Resistance against Japanese Aggression period. Jimaoxin is a special mail created by the soldiers and civilians in North China during War of Resistance against Japanese Aggression's period to transmit urgent messages. There is a chicken feather on the envelope, which means it is urgent. The main line of the film is Hai Wa's Chicken Hair Letter, which is simple in structure, tortuous in plot and full of suspense. It is in the thrilling situation of twists and turns that the film successfully created an artistic image of a firm, witty and brave anti-Japanese hero, Hai Wa, with vivid and meticulous descriptions. This film pays great attention to children's interests from content to form. The opening subtitles are like a comic book, which is opened page by page, making children and children as kind as reading a comic book. At the beginning of each segment, subtitles are written imitating the description of cartoons, explaining the background, environment and mood of the characters, and telling with vivid and humorous narration, which strongly captures the attention of children and children's audiences. Yuanyuan Cai, who plays Hai Wa, has thus become a dazzling child star in the film history of New China.

Behind the scenes, shooting stories

If children's movies with revolutionary history in the 20th century and Private Zhang Ga in the 1960s reached an insurmountable peak, then its origin is Chicken Hair Letter, which was born in the mid-1950s.

A scene that remains in your mind after watching a movie for many years is definitely the most artistic value.

A shepherd boy stood at the top of the mountain, holding a red tassel gun and looking at Pingchuan. There is a tree on the top of the hill. The sun shines and everything is quiet. The narrator's voice began: "Little Hai Wa is the leader of the children's group. Every day, he holds a red tassel gun and stands guard while herding sheep to monitor the distance of the enemy in Pingchuan field ahead. " The focus plane gradually opens: standing under the "message tree", you can see a winding river in Pingchuan, and you can also see many black spots as big as sesame scattered on Pingchuan, which is the watchtower of Japanese devils. The camera was pulled back to the top of the mountain again, and the commentator said, "This is an information tree. As soon as the devil appeared, Hai Wa pulled down the news tree, and the dog dolls and ghost cows on the hillside behind him would also pull down the scarecrow when they saw the news tree fall. The people in the village immediately knew that the devil was going to enter the mountain. "

Suddenly, a long string of black spots climbed out of Getudali in Pingchuan. Hai Wa rubbed his eyes and saw clearly that those black spots were like countless ants climbing to the top of Longmen Mountain. No, the Japanese are out again! The "news tree" on the surrounding hills fell down one by one, and Hai Wa hurried to the "news tree" in Lalongmen Village. On the side of Gouwa and Guiniu, the scarecrow also fell. Suddenly, the bell of Longmen Village rang, and the bell became tighter and tighter. People carrying food and luggage, driving cattle and sheep, rushed into the ravine. The militiamen also gathered together and went up the mountain with weapons.

This is a classic interpretation of the "message tree" in the movie "Chicken Hair Letter". Regarding the anti-Japanese struggle, this group of shots gives children who have never experienced war the most intuitive and emotional understanding.

Like other films in China at the same time, children's films in 1950s and 1960s were burdened with happy childhood in order to adapt to the social situation and political climate in China at that time. Although there were many gaps in the exploration of the style of children's films at that time, it is gratifying that the exploration of China filmmakers from Chicken Hair Letter also left many remarkable classics for the film history of that era. Just the comic concept at the beginning of the film is enough to cheer up the small audience in that era without visual impact. The crew of Chicken Hair Letter accepted the task in mid-September. 1952. After four revisions, it took one year and three months to shoot. Finally, on Children's Day, 1954, this new China children's film, a red classic, was presented to children all over the country, and was later shown in Egypt, the United States and other places. As the first children's film reflecting China's children's struggle against the enemy in War of Resistance against Japanese Aggression period after the founding of New China, Chicken Hair Letter won the first prize of the 9th Edinburgh International Film Festival with 1955, becoming the first children's film in New China to win an international prize.

If children's movies with revolutionary history in the 20th century and Private Zhang Ga in the 1960s reached an insurmountable peak, then its origin is Chicken Hair Letter, which was born in the 1950s.

2005 is the 0/00th anniversary of the birth of China film/KLOC-and the 90th birthday of Gu Yelu, the producer of Chicken Hair Letter. Gu Lao, who just celebrated his 90th birthday, was interviewed by Xinhua News Agency in Shanghai.

Gu Yelu has grown from a milk salesman to a famous entertainer who combines acting, directing and producing. 195 1 year, he loved new China and returned to the mainland with the late director Shi Hui.

Shi Hui was an outstanding film and television actor and director in the 1940s and 1950s, and was known as the "drama emperor". 1953 The original intention of making this children's film is to present a generous gift to the National Day. In order to produce high-quality products, Shi Hui "compiled" many books reflecting the life of farmers in the old areas. Gu Yelu said, "He is a night fairy. He writes about story board at night. I often go to his house after midnight 12 to talk with him about the shooting plan. /kloc-before 0/2 o'clock, he was eating a play and talking about art with his friends; Or date your girlfriend, play poker, combine work and rest and relax. " "Stone swings can bear hardships. When shooting on location, we often lie on the floor of the ancestral hall, and when shooting in Beijing, we sleep on the grass. In art, he is by no means careless. For example, when filming harvesting sorghum, he really wanted to cut a large crop. When filming anti-mopping-up, he will go to the homes of ordinary people, really. I was scared, but I listened to him artistically. After the shooting, the film crew has returned to Shanghai, and Shi Hui will go to the mountainous area of Beijing to build a bunker for the shoot. I don't agree. We had a quarrel with production director Wu, and finally, considering the limited shooting expenses, I had to apologize to him for shooting in Shanghai. " However, in this remake, Shi Hui was injured. In Zhabei, empty shrapnel hurt his leg.

Gu Yelu said that Shi Hui is his favorite actor, and the phrase "I'm not afraid of the hardships of life, but I'm responsible for art" that Shi Hui often said to him was deeply imprinted in his heart.

My younger brother is more heroic than my older brother, so the director asked the two brothers to exchange roles. Thirty sheep boarded a rare train at that time and went to the south with the crew.

Hai Wa is arguably the most successful little hero in China's films. He was afraid, he cried, he was at a loss, and he lost the letter because of negligence. But this not only failed to make people feel his weakness and stupidity, but also made the audience feel the harshness of the struggle against the enemy and the burden shouldered by the characters more truly and credibly, and also made the audience feel the process of growing up with Hai Wa in the exercise he experienced.

Yuanyuan Cai, who plays "Hai Wa", was born into a family of entertainers. Under the influence of his father, Yuanyuan Cai and his brother Anan Cai began to contact the performing arts since childhood.

1952 The director of the movie "Chicken Hair Letter" took a fancy to these two brothers when choosing actors. Xie Jin, the director and assistant director, initially asked their brother Anan Cai to play the leading role in the play-the witty and brave young hero Hai Wa, while their younger brother Yuanyuan Cai played the dog doll of Hai Wa. To this end, the two brothers also went to the suburbs of Beijing to experience life and practiced herding sheep for several months. But after the filming, the director found that the handsome younger brother was closer to the temperament of the little hero than the handsome brother, so he temporarily changed the roles of the two brothers. As a result, Yuanyuan Cai, who was only 10 years old, became the first generation of child stars in New China. Thirty-seven years later, the two brothers established the Chua Brothers Film Company in Macao, which filled the gap in Macao's film and television production industry.

The film was shot in three places: Beijing, Hunan and Shanghai. It was filmed in Beijing, and the guards in Mao Zedong were also used. Gu Yelu recalled: "Chairman Mao's guards also beat the PLA and the Japanese. How many people can't remember. "

The rainy season is the first difficulty in shooting. It snowed heavily within a few days of filming in Beijing. "The film will be filmed in summer and autumn, but it has snowed twice and the snow has not melted yet. I mobilized the People's Liberation Army and the entire film crew to sweep the snow, but I could only take some middle shots and close shots. Xie Jin, the deputy director, suggested going to Hunan to shoot, and it was still a scene of green mountains and green waters. I agreed. " Gu Yelu recalled. But when I arrived in Hunan, I met the rainy season again, and it rained every day. Because it will be shown at 1953, the actors get up early every morning and put on their costumes, and then grab the camera when it rains less. "Yuan Yuan Cai always asks me, Uncle Gu, are you blind? It is still raining. Why do we have to dress up? "

Bad weather can be overcome, but new troubles have emerged.

Anyone who has seen "Chicken Hair Letter" knows that except for "Hai Wa", the sheep, especially the old sheep with a special task and touching fate, has the highest appearance rate. In the south, it is difficult to find sheep for a while. What should I do? The crew decided to take the sheep. In this way, 30 sheep got on a rare train at that time and went to the south with the crew. "In Hunan, every time a place is filmed, the police station sends police to protect the sheep." Some people say that "special protection" is because sheep from the north are not acclimatized to Hunan. Gu Lao explained that it was actually because there were many tigers in Hunan at that time and they ate people. Please ask the police station to protect the sheep, mainly for fear that the sheep will be eaten by tigers. "When I first arrived in Hunan, I saw a coffin in the police station, in which lay a woodcutter killed by a tiger. Isn't there a saying called' sheep into the tiger's mouth'? I can't give the sheep to the tiger. I am worried that I will see tiger paw prints everywhere in the local area, please ask the police station to protect it. " Gu Lao recalled that everywhere, the police station sent a small team of policemen. However, the tiger never came. "How much did the play cost * * *? I can't remember exactly, about 300 thousand. Now a film must be at least several million! " Gu Yelu said.

Hometown of old friends

"The letter has no envelope, but it has a fixed folding method. The urgent letter is called a chicken feather letter with a chicken feather in the middle. "

Chicken hair letters, news trees and movies, which make children look novel and fun, are all special inventions of anti-Japanese soldiers and civilians.

On March 29th, 2005, Xinhua News Agency reporter met Zhang Shenyuan, a 79-year-old survivor of the 1940 CW war in Shanglongshan Village, Dingxiang, Shanxi. He said that since the Japanese came to kill the virus, red flags have been planted on the trees in the south and north mountains of the village, and some people have taken turns to keep watch. This is the "message tree". "I/Kloc-joined the militia at the age of 0/5, and my main task was to keep watch and lay mines. At night, we buried mines in the only way for Japanese troops to enter and leave, and then took them out in the morning for fear of hurting our own people. If the red flag falls on the tree at the top of the mountain during the day, it means that the Japanese are coming. At night, I also take turns to be on duty, two people in a class, one person and one incense. If the sentry finds the enemy coming at night, he will throw grenades and ring the bell to inform the villagers if he has time. There are guerrillas in our village, but because they are too weak, they have not fought directly with the Japanese, mainly to defend the safety of the villagers. "

The "message tree" in War of Resistance against Japanese Aggression, like the ancient bonfire, is an early warning and weapon used by the unarmed people in China for self-defense.

The chicken feather letter in the film is a rectangular letter with an envelope and three chicken feathers in it. When Hai Wa received this special letter from his father, this shot entered the growing memory of millions of small audiences. But for most people, apart from Hai Wa, the trade letter is still a secret.

Wang Zhuan, the 77-year-old head of village children during the Anti-Japanese War, said in an interview with Xinhua News Agency: "Letters have no envelopes, but they are folded in a fixed way. The urgent letter is called a chicken feather letter with chicken feathers in the middle. " He also showed reporters how to fold letters. After folding, leave a long paragraph on the upper end to write the recipient's name, and fold the lower end together to insert chicken feathers.

On April 27th, 2005, Xinhua News Agency reporter met Yan Xiufeng, a young reporter who sent a chicken hair letter in Tianjin. Yan Lao 13 years old began to send letters. "I sent a chicken hair letter without an envelope. I didn't need an envelope at that time, otherwise I couldn't hide it. Fold it into a triangle and hold it in your hand. In this way, if you meet an enemy, pretend to play, then fall down and hide in the soil. The letter is too big to hide. "

Different from these "Hai Wa", Cai, a 9 1 year-old instructor of the Five Heroes of Langya Mountain, is the recipient of the "Chicken Hair Letter". On April 22 this year, Cai Lao recalled to Xinhua News Agency reporters in Baoding that he had received a chicken hair letter from Hai Wa. "If there is no chicken feather on the letter, it means that this is an ordinary letter; Inserting a chicken feather means' urgent'; Inserting two chicken feathers means' extremely urgent'; Inserting three chicken feathers means' 100,000 urgent'. "

It seems that the letter sent by Hai Wa Jr. in the film is really urgent.

Send a message to the devil in Lu Yu, and Xiao Hai breaks into a funeral home for help; He followed everyone and cried his eyes out, tears running down his nose, and almost doused all the lit paper money. The Japanese didn't see any flaw, so they had to leave despondently.

This film is a portrayal of the childhood life of millions of children who grew up in bonfires. It is difficult to verify how many "Hai Wa" and "Wang Erxiao" there were during the whole period of War of Resistance against Japanese Aggression.

Xiao Hai, a 79-year-old famous writer, was a small intelligence agent. After reading "Chicken Hair Letter", he said: "The image of Hai Wa is more credible." Xiao Hai's real name is Yang Zhong, and it was renamed "Tsunami" after joining the New Fourth Army. After the victory of the Anti-Japanese War, the whole country rejoiced and he changed his name to "Xiao Hai". In April 2005, Xiao Hai told Xinhua News Agency about his childhood in Hai Wa.

The following is Xiao Hai's self-report:

1942, Xiao Hai's hometown Nantong was occupied by the Japanese army. Xiao Hai was only a junior high school student aged 14 at that time, but all day long he wanted to join the New Fourth Army and drive the devils out of China. "However, the New Fourth Army stationed in Yangjiayuan suspected that I was young and refused to accept me." Xiao Hai recalled.

At that time, Xiao Hai's sister had joined the army and was engaged in pro-democracy movement and intelligence work in Jinsha District, Nantong City. One night, my sister suddenly woke up Xiao Hai, who was sleeping, and said seriously, "Brother, there is a revolutionary task that doesn't wear a military uniform, doesn't take a gun or a knife, but he is also a little soldier of the New Fourth Army. Are you willing to do this? "

Xiao Hai jumped out of bed excitedly and even said "Yes". In this way, Xiao Hai, who is less than 1.5 meters tall, became a small intelligence agent who contacted her sister on a single line.

Under normal circumstances, when my sister comes back every 10 day, Xiao Hai will tell her in detail the number, equipment, Japanese captain, what the translator looks like, what she did in the countryside, and who became a traitor in the local area.

The work of intelligence personnel is full of danger. One day, Xiaohai went to his aunt's house six miles away to play and learned that a man in the village had defected to the enemy and became a traitor. He asked the man's name, age and appearance, secretly wrote it on a piece of paper, then put it on the paper and hurried back to tell his sister.

When Xiao Hai walked to Guitou Street and was about to turn south, he suddenly saw a group of Japanese devils carrying "plaster flags" and bayonets on their guns coming from 100 meters away. Xiao Hai's heart was pounding because he hid the note. Uneasy and inexperienced, he turned and sprinted. The Japanese found this situation and immediately shouted to catch up. Xiao Hai hurried into the corn field, buried the note in the field, made a mark, and then ran forward. When he met the funeral home, he plunged into it for help.

All the families were crying. When they saw Xiao Hai breaking in, they knew it was urgent. An aunt immediately found him a white mourning robe, a white hat and a pair of filial shoes, and told him to kneel in front of the mourning hall and burn incense and paper money. My aunt told Xiao Hai that Xiao Hai was her youngest son and told her family.

As soon as the arrangement is made, four Japanese devils will come to search. The japs searched everywhere, even the dead people lying on the morgue board. "At this time, the whole family is crying, and I have calmed down. I cried my eyes out with everyone, and my tears and nose were so many that I almost doused all the lit paper money. The Japanese devils didn't see the flaw and had to leave in despair. " Recalling that scene, Xiao Hai is still concerned.

The traitors were finally wiped out by the traitors of the New Fourth Army. This experience and lesson made Xiao Hai understand that the information should be memorized and try not to carry suspected items; Even if you encounter an accident, you should be calm.

1in the autumn of 943, Xiao Hai, who went to the Japanese stronghold to learn about the situation, met a traitor. The traitor knew that Xiao Hai's sister belonged to the New Fourth Army, but he didn't know that Xiao Hai was already a small spy. He stopped Xiao Hai and said, "Don't go, come to dinner with me." Xiao Hai had to follow. At the Japanese military police headquarters, the traitor told the Japanese: "This child's sister belongs to the New Fourth Army." As Xiao Hai was a child, the Japanese didn't pay much attention to him. They said to Xiao Hai, "Hurry back and call my sister first. Next time you catch her, you're dead. " During the trial, Xiao Hai also found another piece of information-four or five female soldiers of the New Fourth Army were locked in a wooden cage.

Xiao Hai pretended to promise the devil, nodded and said, "I know." The Japanese let him out.

After this second narrow escape, the region decided that he could no longer be an intelligence officer. From then on, Xiao Hai bid farewell to the life of George W. Hai Wa.

Just over a year after the outbreak of War of Resistance against Japanese Aggression, almost all the ports along the coast of China fell into the hands of the Japanese army. As a result, the sea passage of international aid to China was completely blocked by the Japanese army. At that time, overseas Chinese donated a lot of money and materials and raised a lot of urgently needed materials in China. The national government also bought a large number of cars, oil, arms and so on with extremely valuable foreign exchange. Pile them in coastal defense ports in Vietnam. Haiphong Port is the starting point of Yunnan-Vietnam Railway. At that time, many anti-Japanese war materials and inward moving machines were transported from this railway to Kunming through Haiphong Port. However, from the point of view of safety and practicality, the Yunnan-Vietnam Railway is threatened to be blocked by the Japanese army at any time, so China should build a communication line to the Indian Ocean in Yunnan, which is located in the rear area. Facts have proved that this consideration is quite strategic. In order to completely block the international passage of China, Japanese imperialism constantly put pressure on the French colonial authorities in Vietnam to stop the government supply in China. 1On September 25th, 940, the Japanese army completely cut off the transportation line between China and Vietnam after landing in Haiphong.

The construction of Yunnan-Myanmar highway is carried out under this background. 1In August, 937, Long Yun, then chairman of Yunnan Province, proposed to Chiang Kai-shek plans to build Myanmar Highway and Yunnan-Myanmar Railway, suggesting that a railway and a highway should be built from Kunming, passing through western Yunnan to northern Myanmar, and finally crossing the ocean. Chiang Kai-shek immediately agreed and ordered the Ministry of Communications and the Ministry of Railways to study and deal with it. 165438+1At the beginning of October, the route of the Yunnan-Myanmar Highway was finally determined through consultations between members of the National Government and the Yunnan Provincial Government, that is, it left Kunming via Shimonoseki, Baoshan, Longling, mangshi and Wan Ding, and then connected with the Myanmar Central Railway in Lashio, Myanmar, and went straight to Yangon. After the route of the Yunnan-Myanmar highway was determined, the National Government specially appointed relevant personnel from the Ministry of Foreign Affairs and the Yunnan Provincial Government as special envoys to Myanmar to discuss road construction in Myanmar with the British colonial government. The two sides agreed that the Yunnan provincial government would build a highway from Shimonoseki to Wan Ding via Baoshan. Myanmar is responsible for building the highway from Lashio to Wanmachi. Subsequently, based on the principle of "local responsibility and central subsidy", the Executive Yuan allocated 2 million yuan to Yunnan to complete the project within one year. However, Long Yun subjectively believes that the Yunnan-Myanmar Highway will be completed in three months. Therefore, he strictly ordered the places along the highway to start construction before the end of 1937, and built a simple highway that could barely be opened to traffic within three months. At that time, Wang Xiguang, the county magistrate of Longling, received an urgent order from the provincial government, and a chicken feather was stuck on the envelope. And a piece of wood. When I opened it, it turned out to be a pair of handcuffs shining with cold light. The provincial government ordered: "The allocation of road sections in this county must be completed within the time limit. If it is not completed within the time limit, the county magistrate will bring his own handcuffs to Kunming. " Huang Hengjiao is an expert on the traffic history of Yunnan. In his research, he found such a story:

At that time, the written pledge to fulfill a military order was overwhelming. Long Yun gave the order and called many county magistrates to build roads in sections. Wang Xiguang is the county magistrate of Longling County in western Yunnan Province. He wants to lead the surrounding counties to build this road. At that time, Long Yun gave him a pair of handcuffs and a feather. We are very strict in China. It means that if you can't complete the order and take you away with handcuffs, it is military punishment. After receiving this order, Wang Xiguang asked the surrounding counties to send people to participate in these things. At that time, it was impossible to have any treatment and remuneration, so I was a little slack. Then the county magistrate Wang went to the surrounding counties to cry and infect them with tears. I hope they send someone, otherwise I will be the target of military punishment in the future, and the effect of crying is not good. What should I do? He pulled out his pistol and said to the surrounding county magistrate, will you send it or not? If you don't send it, my road can't be repaired, and I'm dead. If you don't send me, you will be killed. Whether you send it or not, I'm dead. This scared the people around. If you don't do it, send someone to repair the road. In the process of repair, life is extremely difficult and the conditions are very bad. Some people are a little slack, so he uses a whip, and he is anxious. He lost an eye after the road was repaired. Later, he wrote a long poem. He said, why should I do this to you? I'm sorry to force you to build roads, but in order to protect the safety of this country and everyone.

Long Yun's order to finish the project in three months is obviously only the embodiment of the Yi hero's style of always being competitive, being proud of fighting and being brave and good at fighting, which can't be completed in fact. First of all, this is an arduous road, especially the Xiaguan-Wanding River in the western section is a newly-built river section. It is necessary to cross Nvshan and Gaoligong Mountain in the longitudinal valley of Hengduan Mountains, and also cross Yangbi River, Shengbei River, Cangjiang River and Nujiang River. Not only are there many mountain rapids, but also the altitude fluctuates greatly. The highest point is more than 2600 meters above sea level and the lowest point is only 600 meters. In addition, the lack of trained technicians is also a prominent problem. The General Office of Yunnan-Myanmar Highway had to provide emergency training for some young intellectuals who drifted to Kunming.
