An armchair strategist-Zhao Kuo. During the Warring States Period, Zhao Kuo, the son of Zhao She, a famous soldier of Zhao, studied the art of war when he was young, but his father couldn't beat him in military affairs. Later, he succeeded Lian Po as Zhao Jiang. In the battle of Changping, he only knew how to act according to the art of war, but he didn't know how to be flexible. He rushed to attack and was defeated by Qin Jun, calling the deer a horse-Zhao Gao. Zhao Gao, a traitor in the Qin Dynasty, attempted to usurp the throne. In order to test which ministers in the imperial court obeyed his wishes, he specially gave Qin Ershi a deer and said it was a horse. Qin Ershi didn't believe it, so Zhao Gao made excuses to ministers. The minister who dared not oppose Zhao Gaoyi said it was a horse, and the minister who dared to oppose Zhao Gaoyi said it was a deer. Later, he said that he was a deer minister and was killed by Zhao Gao by various means.

Mao Sui recommended himself-Mao Sui. During the Warring States period, Zhao was king for nine years, and Guo attacked Zhao. So Zhao Sheng and Zhao Sheng were ordered to go to Chu for help, and our public servants volunteered to accompany them. The negotiation between Ping Yuanjun and the King of Chu was fruitless for a long time, so he came to the palace with a sword in his hand and stated his interests. Finally, the king of Chu was moved to send troops to jointly fight against the aggression of Qin.
