China numerology "four kings" in the South Shao North Qiu, East section specifically refers to which four people?

Shao Weihua in "South Shao and North Qiu" is the pioneer, and it is true that Qiu Pingce founded Pingpai numerology, and Li Hanchen's reputation was once brilliant, which is a kind of public opinion. It is said that Duan Jianye is the founder of blind numerology. Although Duan Jianye is famous, as a discerning person, it is not commendable to steal the name of "blind faction".
