After the release, it attracted strong social attention and received high reviews. The film was released in September 2021 and had made 5.7 billion box office by December 1, 2021.

In the movie, whether it is the passionate melody of the fierce war or the melodious melody of the description of the deep friendship between relatives and comrades-in-arms, the plot of the movie is more shocking and moving. The background music not only improves the audience's feeling of watching the film, but also makes the spirit of the Chinese People's Volunteer Army more deeply rooted in the people's hearts.

2 Plot Review of Lake Chosin

On September 15, 1950, American troops successfully landed in Incheon, turning the tide of the Korean war. On October 19, the volunteers crossed the Yalu River and fought in Korea. They soon pinned down the northward American forces on the western front and won the first battle. Due to the emergency of the war at that time, the 9th Regiment, suddenly ordered north, could not change clothes in Shenyang as planned, so the soldiers entered the court wearing thin cotton clothes, most of them without cotton shoes and hats. At the same time, in order to avoid the bombing and detection of American planes, the soldiers have to hide during the day and march at night. It was the worst winter in 50 years in Korea, with temperatures as low as minus 40 degrees Celsius. The number of frostbite suffered by the 9th Regiment skyrocketed because of their thin clothing and lack of fire. Many of the soldiers froze to death in their sleep.

The 31st Regiment of the 7th Infantry Division, also known as the "Polar Bear Regiment," was killed by the volunteers, and its commander, John McClain, was killed. In order to choke the enemy's throat, the third company commander Yang Gensi, was ordered to take more than 30 soldiers guarding the position in Xiaogaoling. Except for three potatoes blackened by the cold, the soldiers' pockets were full of grenades. After trying to beat back the American army eight times, the third company only left Yang Gensi and two wounded. At the moment of life and death, Yang Gensi ordered the wounded with bullets of heavy machine gun evacuation position, holding his explosive bag rushed to the enemy, sacrifice when only 28 years old. .

3 The emotional context of the movie Changjin Lake

In the emotional context of Changjin Lake, Wu Jing's Wu Qianli and Yi Yangqianxi's Wu Wanli are at the heart of the catharsis.

Wujing as wu li represents war veterans, expressed in the film out of the three kinds of emotion, to participate in the Korean war, defend the country showed the immortal patriotic emotion, as a company commander, command combat and cooperate with each other and the comrades in the war won numerous beautiful victory express a rock-solid comrade-in-arms emotion, The commitment to the parents at home and the consideration of the younger brother's life events express the kinship of the flesh and blood.

The main emotional appeal of the part on Yi Yangqianxi played Wu Wanli, and Wu Wanli on behalf of new recruits, new recruits, born calf is not afraid of tigers, but in the baptism of blood and sweat again and again, understand the precious life and the cruelty of war. Wu Wanli is the youngest in the family, went out to war just to always bully his brother respected himself. In the battlefield experienced the blood and blood of teammates, must kill the situation forced, oneself was cut by shrapnel personal experience. Wu Wanli's growth is as the victory of the war is the most important an emotional vent. Wu Wanli carried the young people who had never experienced the cruel peace of war on the war to the confusion of suffering. And when he first into it, in the hands of American soldiers to save his brother Wu Qianli, and then with his comrades fought a beautiful battle, at this time Wu Qianli from the shock at first to fear to the final firm will, it can be said that a generation of young people must be awakened.

The integration of individual perspective not only renders the soldiers' brotherly love, the sense of the same robe, but also conveys their patriotism, family responsibility and yearning for peace. It not only makes the characters more three-dimensional, vivid and full, but also sublimates the feelings of "defending the family and the country" in the film.

In general, the narrative of the film Changjin Lake is narrated by writing people, and the characters are depicted by the things experienced by the characters in the film. At the same time, the characters in the film drive the development of the story, and the background music plays a role in it, making the two complement each other, making the characters more vivid and the plot more deeply rooted in the people's hearts.

Analysis of the background music of Changjin Lake 4.1 The changeable soundtrack style promotes the development of the plot While at the beginning of the film to the American bomber aircraft bombed the yalu river in China marks the prelude to war looms, background music at the moment is the long line of heavy music, the bass long sound of wind foil with heavy atmosphere, the treble string staccato foil out the tension of the situation, that American troops landed in north Korea incheon, background music is turned into the style of the march, strings, woodwind, brass, The strike group is all going on, and it's a symphony in the style of a parade march, in sharp contrast to the long bass music in the background, and it's a demonstration of American military power and arrogance at the same time. General MacArthur told the press, "We will retake Seoul, we will unify Korea, and I promise you this war will be over soon, all going well, by Thanksgiving." And the background music shows the arrogant role of the American army to echo. This remark prompted many viewers to say, There will be no Christmas after Jangjin Lake.

Force closure when the soldiers ready to go to Korea "each boarded the bus, by car, by boarding" after the background music sounded, the music background music also chose the long lines, unlike earlier bombing of the yalu river, the background music in the wind of harmony to major chords, note the string does not do staccato, Instead, the long notes with the main melody are used in coordination with the harmonies of the wind. This collocation is less tense and more warm than the background music of the Yalu River. At this time the atmosphere is set off especially heavy tragic, and wait for the train before the soldiers assembled when the happy atmosphere caused a strong contrast, the soldiers know they may not go back, but still resolutely boarded the train, for the motherland, for the people. It makes the audience realize the cruelty of the war and foreshadows the terrible war after it.

On the train, with 7 repeatedly over long wu li let comrades do tell his brother WuWanLi their brother wu thyme sacrifice process, the train pulled into the tunnel, the snare drum sounded at the same time, in wu thyme sacrifice process, background music has been the snare drum, along a 4/4 do the strength of the relationship between the fixed pace, For the follow-up story of seven heroic results and Wu Wanli growth to pave the way, when Lei Gong said: "The rear of the enemy is the front of my army, the seventh company with their own heavy casualties, for small casualties of our army", joined the trombone, playing a melodic long tone, making the atmosphere settled down, with brilliant color, and highlighted the seventh Company veterans brave, fearless, the revolutionary spirit of death. This is the first recruit Wuwanli growth, the further advance of the plot. When Mei Sheng began to tell his serial number, the background music was added to the string group, and the melody of the descending trombone was tuned up an octave to get the melody played by the high region of the string group. All the instruments played together. The background music was set off by this long line style, and the picture became brilliant. The film came to the first small climax, each soldier began to report their number, it is because of the number of uneven, makes each of them are extremely precious, salute to the heroes.

In Wu Wanli and veterans angry to go home, in the train suddenly open the door, just to see the Great Wall above the sunset shining sunset gorgeous scene. This picture is colorful, rich in front and back scenes, green mountains in the setting sun show gold; And the background sound, long time repetition, drab, depressing noise of the train in a closed carriage bottom noise with WuWanLi depressed, sound material in the extensive use of untreated natural sound, along with dispersion pocked with the winding Great Wall, the wind, singing and see reverberating sound tracks in the open valley echoed in the sound field, At this time, the background music is also timely entered, highlighting the magnificent atmosphere of the sunset over the Great Wall with melodious string music. The gradual addition and cooperation of multiple voices, with rich levels and magnificent artistic conception, give people a kind of border fortress poetry like "do not teach Huma Yinshan" feeling. The eyes of Wan Li and his comrades in arms and the gradually rising and passionate symphony, from their surprise at the beauty of the Great Wall was born out of the determination to defend the country and expectations for the future.

Train was bombed troops walked to north Korea, the company commander WuWanLi observed through a telescope the bodies of our army comrades rocky area, the background music for minor, use among a lot of special effects, such as the first harmonic small 2 degrees, and with the voice of string bow sliding cymbals, these special sound effects increase suspense depression and depressive feeling, will the soldiers heart uneasy, A great deal of inner pressure showed itself. The soldiers had to advance past the body. As the soldiers march out into the open, American fighter jets appear, bringing the drama to a second climax. In the open field with a good view, the enemy planes are heard, and the only thing awaiting them is death. At this time of the story is even more depressed, more heavy, string has occurred in the background of the long sound of loud area small 2 degrees, and then the piano chords followed the tunes column type, and each one on the remake will follow a highpitched pillar chords, nearly 60, the processing speed will be close to the person's heart rate, every shoot like playing on the heartstrings of the audience, At the same time, a solo viola comes out slowly to add a sense of heaviness to the background music. Company commander Wu thousand miles let the soldiers all lie down camouflage bodies, hope so can cheat the United States military aircraft in the air. The U.S. soldiers, who killed our soldiers in the first round at the risk of shooting dead bodies, were ordered to return to the base just before the second round, which saved us from further casualties. After the American military plane flies away, the wounded soldiers just began to scream, background music turned to a major tone, highlight the atmosphere of this one solemn and stirring, screams and the broken limbs of all over the ground and background music contrast, make the audience's mind is deeply shocked, the recruit Wu Wanli in the play also grows up further in this battle.

When the Seventh Company took a rest after winning the battle, the "Battle Hymn of the Chinese People's Volunteers Army" appeared in the background music. The melody was composed of three phrases, which formed a contrast and promoted the development of music through the constant change of music material. Under the background music more than his military began to write to everyone read WuWanLi written self criticism, because the company wanli didn't read the book, so a lot of word is "0", written self criticism became a "0" for books, the soldiers while in exile, and just experience the combat wounded, but everyone still taking pains, "the battle hymn of the Chinese people's volunteers cheerful rhythm, It showed the revolutionary optimism of the soldiers. Through the development of the melody around the major three chords, more shows the volunteers will win the confidence, passionate and generous rhythm sonorous, embodies the momentum of the volunteers unstoppable.

4.2 Accurate song riffs sublimate the role image

The expression of the content of the lyrics is mainly in the form of "one word to multiple sounds", and the melody is more graceful and melodious. It has completed the transition from accompaniment to human voice, from universal patriotism to personal sacrifice, and acoustically across the country's thousands of miles of territory, constructing the film theme of "mountains and rivers are safe" between the waves of the river and the green mountains and rivers, which is full of passionate and romantic revolutionary romanticism poetry.

Tripterygium wilfordii to sacrifice, the background music in vocal aria "yimeng minor", this piece of music is composed of a single passages, music in a single material, on the basis of development, maintain the consistency of the subject material, through minor color, beautiful melody to praise the yimeng landscape, sing people's turn to do the host, "oh, how beautiful home, After the war, he could go back to his hometown and live a safe life, but all this is just a good wish, showing every soldier who is about to die in a foreign land, can not return to his hometown a pity. Make the audience more deeply feel the cruelty of war and volunteer soldiers died of the revolutionary spirit. When thunder Gong says: "Ache, ache dead me." I'm sure no one in the audience will not be moved. No one is born a hero. "Going to war is a hero." At the same time with the theme song "The most lovely people" echo, this faith and power deeply imprinted into the hearts of every audience. There is no loveliest person in the movie, but the volunteers are always said to be the loveliest people. This song is a tribute to the soldiers who fought in the battle of the Changjin Lake in the anti-American aid, there are many words in the lyrics, are telling those lovely soldiers, now our life is very happy, without the war artillery and smoke, now the people live and work in peace and quiet, they are the most lovely people.

As the theme song of the film promotion, The Loveliest Person is a typical juxtaposed single and two parts musical structure. All the juxtaposed parts of the juxtaposed single and two parts musical structure are of equal importance, and any part does not obviously repeat the theme material of other parts, and does not contain explicit reproduction part. "Repetition leads to change". The emotional transformation of the two paragraphs is crucial. Paragraph A is concise. Although the accompanying music is relatively simple and there are no too many instruments, the emotional processing is in place. The second paragraph is warm and exciting, which forms a strong contrast with the first paragraph and sets off the feelings.

Through the comparison of the two passages, the contrast between the verse and the chorus is formed, and the musical material is derived. It shows the historical theme that volunteers deserve the respect of millions of people. "The Loveliest People" expresses the emotion of its name, every volunteer soldier is the loveliest person. As the lyrics say; "Look, there are monuments on the snowcovered battlefield looking at home, tears on your young face, but I know how hot you feel inside." It was immediately obvious that the soldiers of the ice Sculpture Company would rather be frozen into ice than be discovered by the enemy for their activities, even though there were no enemies at the time.
