Not during the opium wars period but I love a movie called To Live. It's about a family's struggles with adjusting for the insanity of the cultural revolution.

Not during the opium wars period but I love a movie called To Live. It's about a family's struggles with adjusting for the insanity of the cultural revolution. Lots of dark humor and I was super impressed by the scope of it. The familys world comes crashing down multiple times as the civil war breaks out and the revolution really kicks off. The movie, director and lead actress got banned from making movies for a few years too so you know it's good.
