Why don't blind people talk about the tradition of opening a library?

Duan Jianye's self-created blind numerology has some merits, but its loopholes are also very obvious. You look at the book and analyze it clearly. In fact, it's not like this.

I once learned the essence from his theory, but I also accepted it selectively. His theory is not suitable for beginners. Because of the mud and sand, the resolution is insufficient, and you will fall into the fog without knowing it.

Theory should serve practice after all. To completely deny the theoretical basis of predecessors and flatter yourself is to eat the rice and smash the pot of the ancients, and there is something wrong with your character. If he really said that, it is far from being a master, and it is for the sake of the villain.
