In the Taoist scriptures, he is called "the true naive martial spirit should help the holy emperor", or "the true emperor" for short. Folks call it "demon Buddha, founder, founder". After the Ming dynasty, it had a great influence throughout the country, especially in modern folk beliefs. According to legend, after the Jade Emperor abdicated, he became the son of Pangu, the third emperor, and gave birth to Emperor Yanhuang. He was once a descendant of Fuxi, the body of a dragon and the ancestor of China.

According to "The Great Sage Zhenwu in Tian Xuan is a vivid mantra", Zhenwu Emperor is the eighty-second change of the Great Sage Laojun. He was born in Rhoda, and the son of King Jingle is better than the queen. The queen dreamed of swallowing Japan, and was born in the palace in October for more than 400 years. When he grew up, he left his family, resigned from his parents and went to Wudang Mountain to practice. After 42 years of success, he ascended to heaven in the daytime. The jade emperor has an imperial edict, and his name is Taixuan. The town is located in the north. The word Xuanwu was originally a general term for seven of the twenty-eight inns in the north. There is a saying in Qu Yuan's "Farewell" in Chu Ci, "Call Xuanwu and rush to the genus". Xuanwu Seven Nights is shaped like a tortoise snake, so it is noted that "Xuanwu is a tortoise snake, located in the north, so it is called Xuan, and it has scales, so it is called Wu".
