The surname source of the surname.

Single origin: It originated from the surname Mi, a diviner of Chu in the Spring and Autumn Period and the Warring States Period, and belongs to the title of religious clergy. In the history of China, divination is a religious act to predict diseases, and it is a common custom in ancient times, which is common in Oracle Bone Inscriptions. In Chu, which is famous for witchcraft and worship of ghosts and gods, it is even more self-evident. According to the historical book Zuo Zhuan's six years of mourning for the public, "King Zhao of Chu is ill, and the river is precious." And sent messengers to "ask Master Zhou". The history of divination foretells good and bad. When King Zhao of Chu was ill, he asked Master Zhou to divine for him. The source of divination is the God of the Yellow River. Although King Zhao of Chu finally refused to sacrifice to other gods on the grounds of "three generations of life sacrifices, but the sacrifices could not be held for a long time", the habit of asking historians for divination when Chu people were sick was certain. In ancient Jingchu area, disease divination mainly includes two aspects: one is to determine the source of the disease. The ancients thought that the disease was caused by ghosts and gods, but each specific patient needed specific divination, which is called "divination for worship". Second, whether the divination patient can be cured can determine the period of recovery or death. This is what Sima Yi, the master of divination in Chu, said: "Sickness can be cured, death can be born, and suffering can be avoided."

There are twenty-eight volumes of the Book of South Turtle in the category of "tortoise shell" in Shu Shu lue in the History of Han Dynasty, in which "South Turtle" is clearly stated, which should be regarded as a manual of tortoise shell occupation in South Chu, and its content is similar to that contained in the above-mentioned Historical Records of Turtle Strategy Biography. Qian is a professional soothsayer who uses divination to predict diseases. For the patient's disease state, it is called chōu(ㄔㄡ (ㄔㄡ), but for the fortune teller himself, it is called "Bu". Unfortunately, in most Chinese dictionaries, the word "Zhen" lacks surname explanation and correct phonetic notation, which is a pity. Xu Shen, a famous philologist in the Eastern Han Dynasty, explained in Shuo Wen Jie Zi: "Sickness is also a disease. From chin to voice. Cut the pigeon ",which means the disease is cured." "Butterfly is cut", that is, the upper voice of Yin (upper voice) is pronounced as ch not u (ㄔㄡ). But as the pronunciation of surname, Xu Shen did not give any explanation for the word "zi". In fact, when the word "Zhen" is used as a surname, it is no longer called "but", which is pronounced as L ù (ㄨˋ). Those fortune tellers, known as "fortune tellers", have been known in ancient times. Most of them have very good primitive medical knowledge and certain therapeutic ability, so they are revered by the world.

Most of the "Sui people" are hereditary, with a long and ancient family history, and some descendants take it as their surname and pass it on from generation to generation.
