I don’t know about Quanzhou, but I worked with Rockies English in a city nearby, Xiamen. They are really close to each other. The principal in Xiamen was originally from Quanzhou so I got to meet some of the teachers there. They seem pretty happy to be in Quanzhou. There are many teachers at Rockies English in Quanzhou. The weather, you are correct to note, is warm in Fujian province.
