I'll give you an answer, too. The Lujinnuo Dental Clinic, 1 meters north of Dennis, the north street of the old city, was opened by Li Wenguang, the director of one hundred famous doctors in Luoyang. One hundred thousand doctors in Luoyang selected 1 famous doctors, but only two in dentistry. How can you compare it with others? Do you admire people's three noes, painless treatment, aseptic operation and no over-treatment? People's disinfection measures claim to be the first in Luoyang, and there are the most doctors and nurses in their patients. What do you think?
