Curing too much medicine was a special class in the medical field in China feudal society, especially after the Ming Dynasty. They used hunger, diet and careful use of drugs to protect the health of the nobility; At the same time, it also avoids the punishment of dismissal, beating, exile, beheading and extinction due to poor prevention and control. Although many emperors in China did not listen to the advice of cure too much and died; But many nobles can live healthily, especially many concubines can live long, and even many eunuchs, maids and bodyguards can die, which has aroused great interest of many modern people.

Now, we humans have begun to pay attention to the quality of life and natural life; However, many modern research materials may be only theoretical speculation, or even taken for granted. Therefore, we might as well review the doctor's historical experience too much, because historical experience is worthy of attention. Liu's family is a descendant of Liu, a medical scientist in the Jin Dynasty in China, and also a descendant of Dr. Yongle in the Ming Dynasty. It is also a rare family of traditional Chinese medicine with a long history in China. The way of keeping in good health and the theory of "three-part rule and seven-part support" founded by Chun Liu are the spoken words of Chinese all over the world. It is also the theory of preventing and treating diseases in traditional Chinese medicine.

Since 1457, the Liu family has used the method of "three-point treatment and seven-point nutrition" to treat various diseases, which is famous for its cancer treatment at home and abroad. It is the only cancer family in China.
