Zhao Kuo. Allusion: During the Warring States Period, Zhao She, a general of Zhao State, defeated the invading Qin Jun and was promoted to supernatant by King Huiwen of Zhao. He has a son named Zhao Kuo, who has been familiar with the art of war since childhood and loves to talk about military affairs. People often say that he is arrogant and thinks he is invincible in the world. However, Zhao She was very worried about him, thinking that he was just an armchair strategist, and said, "In the future, Zhao doesn't need him as a general. In 259 BC, when he attacked again, Zhao insisted on resisting the enemy in Changping (now near Gaoping County, Shaanxi Province). At that time, Zhao was already dead. Lian Po is in charge of commanding the whole army. Although he is old, he still has a good fighting method, which makes Qin Jun unable to win. Knowing that it was not good for him to drag on, Qin implemented a double agent and sent someone to Zhao to spread the news that "General Zhao Kuo, the son of his son, was most afraid of Zhao She". Zhao Wang was cheated and sent away.
