For example, at the beginning, he taught Guo Huang's "Nine Yin Zhen Jing" because Hong Qigong needed medical treatment. As for Guo Jing's "one-yang finger", it is the result of his own use of Yi Deng. It is not a real "one-yang finger" and its power is even worse. This was discovered by Ouyang Feng.
Therefore, we can't teach Eden Kung Fu in Guo Jing and then think that there is a conspiracy without teaching Yang Guo Kung Fu. And judging from the timing of their meeting, Yang Guo's martial arts had reached the point of perfection at that time, and even Qiu was no match for him, not as good as Eden. In the face of such a strong junior, is it necessary for Eden to point out the maze?
In fact, it is difficult for Zhou to promote Yang Guo's martial arts. The only time he can barely intervene is in the valley of desperate love. Taking scissors against Fan Yiweng inspired Yang Guo, and it was obviously not martial arts. There was a fierce "battle" between him and Yang Guo in the later period, but it was just a contest. Although he can gain experience, he is not a martial arts teacher.
As for the other three, they are really excellent masters who have taught Yang Guo Wushu, especially Dong Xie and Du Fu, and can be regarded as his real teachers. Hong Qigong didn't teach him dog stick's thought, but he did teach the moves, and he was half a master. In fact, one of the Five Wonders also "taught" Yang Guo's martial arts. This is Wang Zhongyang. In those days, he left his martial arts secrets on the sarcophagus cover of the ancient tomb, so he was learned by Yang Guo.
