Welcome to drop into our school in the next semester, after August 26th. We have many cyclists, climbers, mountain climbers etc. Few have trekked in the high mountains to the north. Drop in lunch time ( 12.30-1.30 ) and have a coffee I'm sure you'll find someone.
There's a wechat group for KunmingSwap. Also a email Classifieds/newsletter to signup. kmswap.org
See their website for more info.
I have just looked at KunmingSwap, and was going to sign up. However, in the registration page they ask for a lot of personal data that is not needed, unless they are data mining. It could be that the site owner has not considered this a barrier to people signing up, or that data mining is the main purpose.
