What is the difference between traditional blind schools and new blind schools in the eight characters?

Traditional school: a school based on classical books (such as Tian Tian Mu);

Blind Sect: Blind people are fortune tellers. They can't see, but they are imaginative and good at judging their own destiny, which is beyond the ability of ordinary normal people.

New School: A school that emerged in modern times, such as Li Hanchen, is unconventional, but its theory needs further verification.
