Sue has been advertising for 3-4 years, and the whole thing is rubbish. At that time, I went to Lishui People's Hospital and agreed to do it for 2 years. As a result, my child hasn't finished it for more than three years, and the lowest price is 500 yuan every time, once a month, which costs almost 30,000 yuan, and he hasn't done it yet. There's nothing I can do if I want to sue. Who would have thought that this kind of thing would happen to a tooth, and all the documents were not saved. . . .
