What is the identity of Li Beidou, a linen physiognomist?

Li Chunfeng's descendants. According to the information queried in the comic book, Li Beidou in Ma Yi Xiang Shi is a descendant of Li Chunfeng, and his parents are unknown. He learned a little knowledge of Feng Shui with his third uncle, and he can see Feng Shui and look at the gas. However, because there is no serious master, almost no one knows Li Beidou in Feng Shui. "Ma Yi Xiang Shi" tells the story of a life-and-death contest between Taoist Ma Yi, Chen's descendants and talented people in the rivers and lakes since the Northern Song Dynasty, centering on a mysterious vassal bead.
