Some aspects of Chinese culture remained through the cultural revolution, but some previously important cultural features, like those related to music or Buddhism for example, were nearly wiped out. Maybe as a result, to this day some of the biggest hitting Mandarin singers are Taiwanese. In the movie space, HK used to produce lots of great movies, but many of them couldn't be made anymore given the HK takeover and how mainland movie production is now driven by propaganda goals. I hope to see Taiwan pick it up.
