How about Yunnan Aiyou International Travel Agency?

The local people in Kunming tell you never to travel with a group when you come to Yunnan, no matter which group it is. It is best to travel freely if you have the ability. There are too many negative comments on group tours. As a local, I am also very helpless. Those tour guides always come to defile the great rivers and mountains in my hometown. Shopping is always compulsory, and tourists are not allowed to go to the toilet. Although I have been traveling freely and can't comment more, I suggest that you really don't choose to travel with a group. The tourism market in Yunnan is still very chaotic.
