There are two doctors named Hu Yongxiang in Hong Kong. One is a western doctor in Happy Valley Mountain, and the other is an old Chinese doctor in Causeway Bay in CCTV4. I have confirmed it, and I have found my telephone address. Hu Yongxiang did academic exchanges in Fujian last time, and had academic exchanges with Southern Medical University. He has an assistant in Chinese mainland and has already communicated with him. It is unrealistic for patients from Chinese mainland to go to Hongkong to see Dr. Hu. His assistant said.
