Is Ceng Shiqiang a liar?

This man is not a liar, but a cultural scholar, mainly in culture and philosophy. In fact, he doesn't know Yi Li, and his knowledge of Yi Li is superficial, but he is famous for writing books and lectures about Yi in Chinese mainland. The actual content of the lecture is very general, limited to his personal philosophy of doing things, with certain universality, lack of concreteness and profundity, and low academic value. He is not an actual combatant of Yi-ology and has no practical experience of exercise. Therefore, he can only regard Yi-ology as a philosophy of doing things, and has no in-depth research experience in predicting the number of skills. Generally speaking, this Weng has high literacy and good popularity. He likes to listen to many of his lectures, and his philosophy of life is also very good.
