Blind fortune teller

Who are the famous figures in numerology for the blind?

I have heard of two legends: Hao Jinyang and Xia Zhongqi. In fact, Duan Jianye, Xing Mingfen and Su, who were exposed by the blind, all exist in name only. There is no real skill, and it is just a little material. There is a teacher named Ren who has contact with the blind stream, and his information content is quite good. Free evaluation of evidence in actual combat is definitely different from that in theory. How many real blind experts talk about theory? It's all about exports. This is certain. Nowadays, the field of Yi studies depends on fame and skill.
