In late November 1950, in Changjin lake, North Korea, the temperature was minus 40 degrees Celsius. The snow fell from the sky and the earth was covered with cold ice. The retreating U.S. troops groped forward on guard. Suddenly, they found rows of Chinese people's volunteer soldiers lying opposite. These soldiers in thin cotton clothes carry guns, and everyone keeps fighting. But in the face of the invading enemy, they did not fire. When the US Army approached, it found that the whole company of volunteer soldiers had been frozen into "ice sculptures" - this scene appeared in the National Day Film Changjin lake. The picture of volunteer soldiers frozen into "ice sculptures" is also reflected in the scene of "ice and snow Changjin Lake" at the memorial hall to resist US aggression and aid Korea in Dandong City, Liaoning Province. "The 'ice and snow Changjin Lake' reproduces the heroic scene of the Changjin Lake battle on the east line of the second war to resist US aggression and aid Korea in the form of sound and light. Through the main color of blue and the stacked ice and snow, the audience can intuitively feel that the main enemy faced by the volunteers in this battle is cold, which is as terrible as shells." deputy curator of the memorial hall to resist US aggression and aid Korea Zhang Xiaoying, a research expert on resisting US aggression and aiding Korea, said. According to Zhang Xiaoying, the 9th corps of the volunteer army originally planned to rest and change clothes in Liaoyang, Shenyang and other places. However, due to the emergency situation of the war, more than a dozen trains stopped in Shenyang for only a moment and rushed to North Korea. "During the train stop, the Northeast Logistics Department was very surprised when it saw that the troops entering the DPRK were wearing such thin clothes. It immediately mobilized cadres and soldiers to take off their clothes and hats and replace them. However, due to the short parking time, many clothes and hats did not have time to get on the train. In this way, most of the soldiers of the 9th Corps entered the Changjin Lake area in big eaves hats, rubber shoes and thin cotton clothes." "Most of the soldiers of the 9th corps of the volunteer army come from the South and don't know much about the weather in the north," said Zhang Xiaoying. The Changjin Lake area is the most bitter and cold area in Northern Korea. "During the campaign, there was heavy snow in the theater. The officers and soldiers were poorly dressed, lacked food and ammunition, and suffered from hunger and cold. Some troops could only eat frozen sorghum rice once a day or two, resulting in serious frostbite and attrition. In addition, due to the severe cold weather, many mortars equipped by the volunteer army could not be used, the bolt could not be fired, and the communication was extremely blocked." During the visit, commentator Gao Zhenzhen told a story: in early December 1950, volunteer soldier Zhu Yanfu was ordered to join the army to resist US aggression and aid Korea. In the battle of Changjin lake, Zhu Yanfu's company braved the severe cold of minus 30 degrees Celsius and fought bloody battles with well-equipped enemies for three days and three nights. Only he survived in the whole company. "Zhu Yanfu was injured and unconscious during the battle. His body was seriously injured by the cruel battle and bad weather. 93 days after 47 operations and coma, his hands and limbs below his knees were amputated, his left eye was blind and his right eye vision was reduced to 0.3." in 2019, Zhu Yanfu was awarded the national honorary title of "people's model". Even under such harsh conditions, the volunteer army has completed its strategic mission. The reporter learned at the memorial hall of the war to resist US aggression and aid Korea: on November 27, 1950, the 9th corps of the volunteer army launched a fierce counterattack against the general offensive launched by the 10th army in the eastern theater. On November 28, it completed the division and siege of the US Army in the Changjin Lake area, and surrounded the 1st division of the US land war and the 7th Division of the infantry in liutanli, Xinxing Li, xiajieyuli and other places; On the evening of November 30, the 27th volunteer army launched an attack on the 31st regiment of the US Army in xinxingli; After the victory in the xinxingli battle, the 9th corps of the volunteer army adopted the encirclement, pursuit and interception tactics in view of the enemy's breakout and withdrawal to the South on the eastern line. After several days of fierce fighting, it gave a annihilation strike to the 1st division of the US Marine war and the 7th infantry division, opened the battle situation on the eastern line and ensured the lateral and rear safety of the volunteer army on the western line. "During the period when the memorial hall collected cultural relics from the society during the period of resisting US aggression and aiding Korea, the children of song Shilun, commander and political commissar of the 9th corps of the Chinese people's Volunteer Army, donated the telescope and carbine he used during the period of resisting US aggression and aiding Korea to the memorial hall." Zhang Xiaoying said. In addition to the "ice and snow Changjin Lake", there are scenes such as "fierce battle Yunshan city", "steel transportation line", "invincible tunnel" and "fierce battle Shangganling" in the memorial hall to resist US aggression and aid Korea, which reproduce the glorious history of the great war and movement to resist US aggression and aid Korea from different aspects. "By reproducing these scenes, the Memorial Hall shows the great spirit of resisting US aggression and aiding Korea and expresses infinite remembrance of the martyrs," Zhang Xiaoying said.
