Looks as if the Yuncheng of 2001-2014 is a thing of the past.

I can clearly imagine how they treat non-native speakers from West Africa.

Since I used to see it first hand, no imagination needed.

Havana is gone along with the owner and dance instructor.

Two eras in YC.

2001-2008
4500-6000/month
FTs would all hang out., do scavenger hunts, could save good money, buy a local apartment, go on holiday, buy a car, start a restaurant, travel all over. Cost of living very low.

2008-2014
5000-6500/month
FTs would not hang out together as much, save some money, those there from 2001+ started a business, those who married bought an apt, bought a car, travelled. Cost of living low but rising. Lots of work at many schools to be had.
Paolos, Cafe Italia, Howards Kitchen, and the Walmart all made life easy.

2014+
5000/month
Cost of living no longer low, no community or camaradarie.
Hostility from locals.

2018
Paolos new owner, HK closes, fewer teachers, no permanent living arrangements, teachers shuffled around each month, West Africans paid much less than in 2001.
All long termers leave, as in the exodus of Beijing bloggers in 2013-14.

Seems the time for teaching in China is over.
