The chinese internet is mainly baidu, the contents of which is just cheap entertainment.
Honestly, modern chinese youths seem no different from millenials elsewhere, and it's hard to find stuff outside the mainstream because censorship.
The best thing about chinese language is the ancient literature.
I'd argue Hong Kong's culture is in many ways more attractive, but they all speak english for the most part anyway. You can learn cantonese, but it's fucking hard (6 tones + 3 entering tones) and not even strong in business anymore since mandarin is kind of the english of the chinese world (other than, you khow, english!)
