First, the identity of Guiguzi As a very wise person, Guiguzi is also proficient in metaphysics, theology, medicine, art of war and so on. People in the Spring and Autumn Period and the Warring States Period opened the Ghost Valley Gate. Because of his extraordinary wisdom, later generations called him the father of Wang Chan. He is a successful person who integrates political and military education. Su Qin, Zhang Yi, Pang Juan and other brave men who can influence a country's life and death have all been taught. It is also the masterpiece Guiguzi, which still has extraordinary influence today.
2. Many people have raised such questions about Guiguzi recorded in history from ancient times to the present. Does Guiguzi really exist? Why can't you see anything about him from some official history? In fact, guiguzi did exist in history. We can know from Sima Qian's biography that Su Qin studied under Mr. Gui Guzi. And can the same be obtained from historical records? In Biography of Zhang Yi, we can know that Zhang Yi also learned skills from Mr. Guiguzi. In the Eastern Han Dynasty, Wang Chong also wrote a book called Guiguzi, the originator of military strategists, and so on. In fact, the record of Guiguzi is not necessarily absent in the official history, but it may be that Qin Shihuang burned books to bury Confucianism, and the lack of future generations cannot be made up.
Mr. Guigu dedicated the essence of his life's study to Guigu, leaving it for future generations to learn and understand. It's a pity that what we see now is not the original. The original has disappeared. What we are seeing now has been sorted out and repaired by several dynasties, but it still plays a very important role for us and has far-reaching significance for historians to study contemporary history.
