There was the legend August King Shennong in remote antique China, who tasted various herbs to find medicines for treating people’s diseases. Chinese medicine has an extremely long history, and medical books in China appeared much earlier and were more abundant than any other civilization. Chinese medicine also took the lead in the world in the Han dynasty. First, the official medical system was rather advanced, and both the royal court and the imperial court had a specific medical department headed by the taiyiling (or the grand royal or imperial doctor), who took charge of treating the royal members or the nonroyal officials and civilians respectively. Second, the imperial government of the Han dynasty took measures to compile and collate existing medical books, including renowned books such as the Huangdi Neijing and the Shennong Bencao Jing, which have been handed down to the present. Third, there were many well-known doctors in the Han dynasty, e.g. the sage doctor Zhang ZhongjingZhang Ji(张机), also known as Zhang Zhongjing(张仲景) and the divine doctor Hua TuoHua Tuo(华佗), as well as many medical books, e.g. Shanghan Lun.
