Can you give me recommendations, of good international schools to go to Kunming to study Chinese? And how to apply to them from here, thinking that borders will remain closed form more months?

Hey Ben, not sure about where you meant when you said “from here”, and though I'm no expert in validating info provided online about this, this is the e-mail I found of Mei's Mandarin School in kunming: kmmandarin@126.com, you can write them up and make your enquiry. Hope it works for you.
