Su Qin was born in Luoyi (now Luoyang East) in the Eastern Zhou Dynasty. When I was young, I studied with Zhang Yi under Mr. Guigu in Yangcheng, Yingchuan (now Dengfeng County, Henan Province). After his academic success, he went to the Eastern Zhou Dynasty (when the Zhou Dynasty was reduced to a "state" and split into two states) and asked Qin to be an official to show his ambition, but he was not hired. Su Qin was not "disheartened" when he got such treatment. Instead, he went back to his hometown and studied harder. For more than a year, my head was hanging on the beam and my teeth were biting (which left a story of "hanging on the beam and stabbing my teeth"), and I studied books on the art of war, medicine, economy and law. Fully studied the specific situation of each country at that time. At that time, among the nations, Qi, Chu, Yan, Han, Zhao, Wei and Qin were the most powerful, and among the seven countries, Qin was the strongest. Therefore, after repeated thinking, Su Qin initially formed a strategic idea of promoting the six-nation alliance to jointly resist Qin, that is, "integration". Out of confidence in his new strategic thinking, Su Qin once again left his hometown to lobby in various countries. Who knows, his departure has made China a first-class "strategist" in history, which can be said to have changed history.
