The earliest record of "Min" can be found in China's ancient encyclopedia Shan Hai Jing, Volume X: "Min is in the sea, with mountains in the northwest and Zhongshan in the sea." Xu Shen wrote a monograph on Chinese characters in the Han Dynasty, which said, "Fujian, Southeast Vietnam, snake species, insects, door sounds." The snake species here is the snake clan, that is, the clan that believes in the snake god. The smallest characters are created by the sounds of insects and doors. The word "worm" is interpreted as "snake", that is, the clan that worships snakes at home, and the totem of Fujian and Vietnam people is snake. Fujian people are defined as a group that worships snakes. What can be used as evidence is the writing of the word "people". The ancients called snakes long worms, which can be interpreted as "Fujian is a mountainous area with many snakes and insects, so the word" insects "is added under the door to show its characteristics".

Fujian people have an indissoluble bond with snakes. For thousands of years, snakes have profoundly influenced Fujian people's religious beliefs, folk customs and spiritual culture, and formed a unique cultural custom of worshipping snakes.

Fujian has been called "Min" since ancient times, and "Min" means there are snakes in the door. Xu Shen's Shuo Wen Jie Zi in Han Dynasty did not classify it as a phylum, but as an insect family, and its definition was "Fujian, Southeast Vietnam and Snake Species". In ancient Baiyue, as a main branch of Yue nationality, Min Yue nationality lived in Minjiang River valley, southeast hills and coastal snake-affected areas, and regarded snakes as a symbol of clan or as a totem, and regarded snakes as ancestors of clan and worshipped them. Therefore, Min Yue people have long maintained the custom of worshipping snakes, "wearing scales-like tattoos", and have the habit of cutting off tattoos and depicting snakes on their bodies, in order to pray for avoiding fierce animals.
