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
Some of the lower effort Sino-Japanese war dramas that depict the Americans giving air support to China just have random white people talk vaguely military speak and then the subtitles are completely different. They can't get away with it much now because English proficiency in China is a lot more common, but it wouldn't be unusual 10 or 15 years ago to have the pilot say random shit like "10-4 florida alligators roast beef" the subtitles in Chinese are just like "We must coordinate the bombing runs along the mountain pass"
