Aside from the listed movies, I have a TV show to recommend called "In the Name of the People," which I'm literally HOOKED to. Here is a playlist with English subtitles: https://www.youtube.com/watch?v=A74YChOkSpY&list=PLJpCdaWK6PVpeWbeUSjw4dBWt5IKK5Buj. The show is about an anti-corruption taskforce dealing with high profile cases, cadres involved in various schemes, etc. Show really caused a whirlwind of confusion in the west because it broke through the notion that the CPC "censors" anything that portrays it in a potentially negative light. I really like the message the show brings across, and the need to reinforce the notion of serving the people wholeheartedly, while smashing opportunists and those who try to bring down the cause of socialism.
