In ancient times, doctors had two names, doctor and doctor, which were mainly formed because of geographical problems. Most northerners call doctors "doctors" and southerners call doctors "doctors".
The doctor said that it originated in the Xia Dynasty. The Book of Rites says: "Xia Houshi has 100 officials, three officials of the son of heaven, nine ministers, twenty-seven doctors and eighty-one scholars." There were also officials, ministers, doctors, scholars and other officials when Zhou Li was formulated, which was a new concept in the Warring States period-"scholar-bureaucrat". During the Qin and Han dynasties, there were official positions such as admonition officer, doctor of traditional Chinese medicine and doctor of Guanglu. Until the Tang and Song Dynasties, the official position of admonition officer was still retained, and it was not abolished until the Ming and Qing Dynasties.
