Why is Guiguzi so powerful in history? Are there any books in circulation?

Guiguzi is a real person, and all his disciples are excellent. During the Warring States period, his disciples were basically in charge. Guiguzi lived in seclusion in Yunmeng Mountain all the year round and taught art here. Zhang Yi, Su Qin, Sun Bin, Pang Juan, Mao Sui and Chui Fu are all his disciples. Among Guiguzi's disciples, Xu Fupai is behind Sun Bin, Pang Juan, Su Qin, Yi Cheung and Mao Sui.

Sun Bin and Pang Juan studied the art of war, and they also knew martial arts and anecdotes. They played in the time of Qin Xiaogong, the great grandfather of Qin Shihuang.

Zhang Yi and Su Qin majored in vertical and horizontal arts (lobbying, diplomacy). They died only 1 year after they came out of the mountain in the era of King Hui of Qin and Zhao Haoqi, the great grandfather of Qin Shihuang.

Mao Sui and Xu Fu are the late disciples of Mr. Guiguzi.

Mao Sui played in the era of Xiang Zhuang Wang (Lv Buwei was in power), the father of Qin Shihuang, and volunteered to hijack the king of Chu when he joined the alliance of Wang Wei, the king of Chu.

Xu Fu is a close disciple of Mr. Guiguzi. Learn to explore the valley, qigong, cultivate immortals, and also know martial arts. When he came out of the mountain, it was the time for Li Si to play before and after Qin Shihuang ascended the throne.
