If you look at strategists? How to evaluate guiguzi?

Lian Heng of Qin is actually very simple, that is, opposing and breaking the alliance. In order to break the alliance, Qin did not make a Covenant with the six eastern countries, and no one would say no to the immediate interests. The alliance of the six countries is originally due to interests. As long as it is the temptation of interest, it can be broken. After analyzing the six countries of vertical integration, it is not difficult to disintegrate vertical integration. Sun Bin and Pang Juan, the masters of Guiguzi, both worshipped under Guiguzi's door and were called Mr Guiguzi. According to legend, he studied Taoism with Taishang Laojun. And he himself wrote a lot about marching, Taoism, divination, and watching people look at houses. Even a state is famous for its ups and downs. Zhang Yi, a disciple of Su Qin who studied with him, followed him to learn vertical and horizontal skills. As a result, Su Qin became the seal of the six countries, and Zhang Yi even used the method of attacking from far and near to make Thailand unify the world. As for Sun Tzu's art of war, it was also learned from Guiguzi, and later generations called it Sun Tzu's art of war. All the art of war is unparalleled. In fact, he is also one of Guiguzi's disciples. ?
