I suggest you go to Dashan Yuande in Taiyuan, Shanxi. I decided to go to this restaurant after a lot of selection. Basically every teacher says that his or her family is good, but the conduct of each teacher is really different. My two girls started their careers there, and they are very satisfied. The teacher is indeed very knowledgeable and knows everything. I really admire him, he is so professional. And it's not like the naming hall on the street. This is the first time I've seen such a formal one. You can go there and have a look.
