I'm very confused. Karaoke definitely exists in China. Maybe they go by a different name: KTVs.

Yes. Stand-up comedies are also huge in China:

- "Single-standing Comedy" in Beijing: http://www.danlirencomedy.cn/ and https://www.youtube.com/channel/UCeN0myzkjm2BDjaBZ5C3Qng

- "No-name Comedy" in Nanjing: https://www.wumingxiju.com/

- Fun Factory in Shanghai: https://www.linkedin.com/company/%E4%B8%8A%E6%B5%B7%E7%AC%91...

Cunningham's law at work.

In the US, karaoke exists as a form of standup comedy.
