I know one, who is over 70 years old now and has more than 50 years of experience in traditional Chinese medicine. I used to have my own pharmacy and clinic on the street, but now I have moved to my home. Near the opposite side of Litang Kowloon Hotel in Nanning, next to Weizhen Wedding Dress Hall. It's called Baokang Clinic. The old Chinese doctor is good at conditioning his body. I just saw it there on National Day. I also felt his pulse and prescribed many oral liquids to recuperate his body. It's good. Family brought it. It's trustworthy.
