If we’re talking about cultural exports, then I would highlight the three body trilogy, which is a Sci-fi trilogy which actually did become quite popular in the west. China of course also has quite a big gaming industry (genshin).

I mean, China has lots of ‘cool’ things, but it is actively suppressed by the media landscape in the west. It should also be noted that China lacks soft power only in western countries. According to the Bennett Institute, China is more popular in the global south than the US.
