I live in China and buy local beans exclusively, China isn’t particularly well known for being a bean producer - and most people here don’t drink coffee, though it’s growing - but down in Yunnan, in the border region to Vietnam, Laos and Myanmar are a bunch of farmers and roasters, and they make excellent stuff.
Unfortunately none of them have any websites and are only available via Chinese social media or messaging apps, but if you come across any Yunnan roasts by chance, give it a try!
