Who is the legend of Guiguzi in Mi Yue? Is Zhang Yi an apprentice of Guiguzi?

Guiguzi, surnamed Wang, also known as Xuanweizi. A prominent figure in the Warring States period, the Huaxia nationality, had four meat moles on his forehead, like a haunted house. He is a famous thinker, a representative of Taoism, a master of art of war and the originator of military strategists. Proficient in the study of a hundred schools of thought, he called himself Mr. Ghost Valley because he lived in seclusion in Qingxi Ghost Valley. Military strategists respect him as a saint, strategists respect him as an ancestor, fortune tellers respect him as a founder, strategists respect him as a saint, famous artists respect him as a founder, and Taoism respects him as the bodhi old zu of Wang Chan. Guiguzi's master is Lao Zi, the founder of world dialectics, the father of world philosophy and the top ten writers in the world.

Shi Zi's Zhang Yi is indeed Guiguzi's apprentice. His most outstanding disciples are Su Qin, Bai Qi, Li Mu, Mao Sui and others.
