DOU Hanqing, a doctor in the Jin and Yuan dynasty, was good at acupuncture. In 1218, the 23-year-old DOU Hanqing married a daughter of medical family in the Qingliuhe area. DOU Hanqing began to learn medicine from the family. From then on, he learned acupuncture from SONG Zihua, LI Hao and his son (famous doctors in Shandong), XIE Xianzi, QIU Changsheng and others, and his achievements were great. DOU Hanqing was not only good at acupuncture but also was pleased to teach students. WANG Renzheng and his son, ZHENG Yu, ZHU Yanhui, XU Kan, LIU Zhizhong and LUO Tianyi were all his students and a few his hometown people also learned from him.
