A screenshot from the official “Battle of Changjin Lake” trailer on Youtube. A former investigative reporter Luo Changping was recently arrested for mocking the newly released propaganda movie, “The Battle at Lake Changjin” (or Chosin Reservoir), a war drama featuring the People's Volunteer Army (PVA) during the Korean War (1950–53). The film was released as part of the 100th Anniversary of the Communist Party of China. With a 200 million US dollar production budget, the movie is co-directed by award-winning filmmakers Chen Kaige, Hark Tsui, and Dante Lam and stars top actor Wu Jing. The film was released on China's National Day, and mainland Chinese box office earnings passed 4 billion Chinese Yuan (600 million US dollars) in less than 10 days. The film tells a story of the Chinese Volunteer Soldiers’ self-sacrificing heroism which helped them dramatically defeat the US army in the battle of Chosin Reservoir. The battle took place between November 27 and December 13, 1950 — one month after former Chinese leader Mao Zedong officially entered the Korean War. The three-year war between the Soviet-backed North and United Nations-backed South Korea was triggered after North Korean military forces crossed the border and entered South Korea on June 25, 1950. Under the slogan “resist the US in support of Korea” (抗美援朝), Mao ordered the Chinese liberation army to attack the United Nation troops, which was composed mainly of US forces, in North Korea to prevent the unification of Korea under capitalist forces. To avoid declaring war against the UN and US, the Chinese troops were dubbed the “People's Volunteer Army (PVA). About 3 million Chinese civilian and military personnel served in the Korean War. During the war, 120,000 Chinese soldiers from the PVA's ninth army were sent to the battlefield in the middle of winter to attack 30,000 United Nations troops in Chosin Reservoir. The Chinese volunteer army was so poorly equipped that tens of thousands froze to death as the temperature in the Chosin Reservoir reached minus 30 degrees Celsius. According to official Chinese reports, the army recorded 48,156 casualties during the battle, with nearly 29,000 being non-battle-related deaths. As for the UN troops, they lost 17,843 lives, with 7,338 killed by the brutally cold weather. However, the latter managed to retreat and eventually evacuate 98,100 refugees and civilians who wanted to escape the Soviet-backed military regime out of Northeastern Korea, a region surrounded by the Korean People's Army (KPA). The choice of the battle as a patriotic propaganda film is controversial, as the Korean War was an incredibly painful period for both China and Korea. It is estimated that North Korea and China each lost between 200,000–400,000 soldiers while the South Korean army lost 162,394 and the American army lost 36,574 lives. The Soviet Union air force lost 335 planes and 299 lives. China's intervention in the Korean War was largely controversial until recent years as the war caused huge causalities on all sides. More than 3 million Korean civilians died in the war. As pointed out by Adam Ni from Chinese political news analysis site, the battle Chosin Reservoir was considered a “failure at massive cost”: even before the battle ended, already handed in to Party Centre a doc titled “9th Army Group self-criticism on the battle on the eastern front”, saying that it was a failure at massive cost. Today, this failure is celebrated. — Adam Ni (@adam_ni) October 6, 2021 However, in China today, reflecting on the war can have grave consequences. Former investigative reporter, Luo Changping was arrested for “infringing the reputation and honor of national martyrs” after he wrote the following comment on Chinese social media: 半個世紀之後國人少有反思這場戰爭的正義性，就像當年的沙雕連不會懷疑上峰的『英明決策』。 After half a century, people in this country seldom reflect on the cause of this war. The situation is like the frozen troops back then, they did not question the “acute decision” from the above. While most negative comments about the movie and critical comments about China's intervention in the Korean War have been suppressed and censored, patriotic messages spread on social media. One netizen @fangshimin placed two video bloggers’ so-called “personal” interpretations of the film together to demonstrate the propaganda authorities’ effort to advocate for a “hot-blooded” (血性) patriotism, which means a willingness to fight for the country: 《长津湖》宣传通稿出新版了。 pic.twitter.com/ZUu2W3yCyN — 方舟子 (@fangshimin) October 11, 2021 Here come the propaganda script of “the Battle of Changjing Lake” It is common to see pro-Chinese government bloggers spreading authorities’ talking points. One notable example was a flood of video clips on Uyghurs’ life in Xinjiang.
