visiting but don't want to do tourist things, advice?

hellooooo. my deal is that ive studied chinese for 10 years and speak mandarin well. i've already done a lot of touristy stuff in china. on this visit i just want to meet people and live real life. i want to make friends, attend public events, visit bars where strangers socialize with each other. I want to see cool stuff. Like last time I was in shanghai i stumbled on the marriage corner in people square. super interesting and talked to a lot of cool people.

i havent been in china for a while, but my understanding is that you don't just baidu search for these things, is that right? event information is published on specific wechat accounts and in private groups? could i possibly get added to a group for international students or something so that i might see public events?

gym recs? bar recs for socializing? are there language exchange events? are there things like salsa dancing in chengdu?

thanks fellas <3
