It's einsun, Kunming.
There are two trainings, one is Xinhua and the other is Ai Yinsun.
Ai Yinsun has a NA course and examination room, which is located in the business building 1 building of Nanjiang Hotel.
There is NP course, but it seems to be sponsored by Yunnan University. The address is different, but the teachers are the same. After studying, they will take the NP exam in Kunming.
As for IE, according to my teacher, he took four in Kunming, and all of them passed. He is also in charge of training in Kunming, but I feel a little hung up.
