The system of medical women in North Korea was established in the sixth year of Emperor Taizong [1406]. Because the concept of difference between men and women is becoming more and more strict, the inner palace and the harem are taboo to be treated by male doctors, even if they are terminally ill, they will not seek medical treatment, which will eventually lead to death. Being a doctor is a kind of nursing work, and most families in China will not let their daughters do these things. So at the beginning of the system, a servant girl was designated as a pariah. At that time, all the female courtiers who chose Hanyang office were studying in Huimin Department. At the local level, officials and servants aged 10 to 15 will be selected to receive education at Huimin Department, and then sent back to their hometown to engage in medical work, so that local women can also seek medical treatment when they are sick.
