I think it is very beautiful. The first stage of Professor Huang Yuanliang's career moved me very much. If it weren't for these doctors who silently contributed behind the scenes, the dental industry in China wouldn't have developed to this point at all. I'm looking forward to the next story. At the same time, I am also very grateful to Baisong Dentistry. If they hadn't invested in this documentary, I wouldn't have known the story behind the dentist. Praise the dentist, praise the white pine dentistry.
