There is an old Chinese doctor named Huang in Shuijinshe (Xijiekou Alley), and his medical ethics is very good. He often spends ten to twenty dollars to treat minor illnesses. He used Chinese and Western medicine to prescribe medicine according to his illness, which was not worse than Bian Que Huatuo, but it was rare. In recent times, I often wanted to study, and I was polite because I never left my body. I was born in an alley for at least 30 years.
