Chinese films that are a must watch

I've long been curious about Chinese films and seeing the recent post on this sub on Korean films led me to make this post. It's interesting how rare they get mentioned in this sub as I'm guessing with China's age and massive population, surely they'd be spewing out high quality films.

I've seen a lot of Wong Kar Wai's works like In the Mood For Love and Chungking Express. They're easily some of my "objectively" best films I've seen, as well as some of my personal favorites.

Apart from his films, what other Chinese movies should I see?
