The Battle at Lake Changjin (2021)

I went on a bit of a research expedition and learned that Mao’s eldest son, Mao Anying, who was killed in 1950 by a US bomber during the Korean War briefly depicted in the movie, studied in Moscow, petitioned Stalin to send him to the front during the WW2, got his wish, and served as an artillery officer, during the final Battle of Berlin including. Also had no idea Mao had 10 children lol
