There is a director Jin Lei in Chengdu 363. He is very famous in Beijing. Just say my friend went to see him, and he was embarrassed to let you register. He must be given priority. If they are not cured in the future, you can come to me and complain about him.
Don't worry, he has a lot of experience there and has been an old director for more than ten years. He was one of the earliest people who made gamma knives in China.
Moreover, the equipment is also very stable.
