What is Duan Jianye's eight-character level?

Duan Jianye's eight-character level is average. Duan Jianye founded the theory of blind work, which was too foggy. Theories are always contradictory. It is not recommended that you waste your time reading Duan Jianye's books or classes and study Duan's theory in depth. You found many loopholes, some life examples were too far-fetched to explain, and the image was too far-fetched, which really misled the majority of easy friends. His theory of blind schools is uncertain, and every course is changing, so it is impossible to use it in actual combat, and the actual combat level is average.
