I don't know if you have heard of Zhang Xiaotian, the director of Sheng Jiaxin, where I had my bone grinding operation. He has more than 20 years of experience, showed me many cases, and introduced several people who had just finished surgical observation. When I talked with them, I said that Director Zhang Xiaotian did a good job. It was already afternoon when I woke up after the operation. Director Zhang Xiaotian is still on the operating table. He came to greet me at night and told me the precautions. It was very warm. Now the recovery is very good, the effect has come out, much better than before.
