One,

Tian Shan guarded Jimo in an attempt to sow dissension and spread the news that Le Yi failed to capture Jimo, so as to get rid of Jiang Yan Leyi and become king in Qi. At that time, the Qi people had not listened to him, so they postponed the attack on Jimo. What Qi is afraid of is that Yan has changed. Sure enough, the prince took the bait and replaced it with a riding robbery, so he had to flee to Zhao. Qi people were overjoyed, and Tian Dan defeated the Yan army with a fire bull array.

Second,

In Romance of the Three Kingdoms, Zhou Yuqiao killed rebels Cai Mao and Zhang Yun who were proficient in water warfare, which is also a famous example. Cao Cao led the so-called 800,000 troops to cross the Yangtze River and unify the South. But Cao Cao's troops are all composed of northern cavalry. They are good at playing horses, but they are not good at fighting water. Only two commanders who are proficient in water warfare, Cai Mao and Zhang Yun, can train the water army for Cao Cao. Cao Cao treats these two people like treasures and gives them preferential treatment. On one occasion, Zhou Yu, the coach of the Wu Dong team, was shocked to see Cao Jun on the other side queuing in the water, and he was well organized and very good at it. He wants to get rid of these two big troubles. Cao Cao knew that Zhou Yu was a promising young man and a military wizard, and wanted to win him over. Jiang Gan, the counselor, claimed to be an old friend of Zhou Yu and was willing to cross the river and surrender. Cao Cao immediately asked Jiang Gan to cross the river to persuade Zhou Yu. When Zhou Yu saw Jiang Gan crossing the river, a double agent was already brewing. He warmly entertained Jiang Gan, and Zhou Yu was accompanied at the banquet to show off his strength, and stipulated that only friendship should be discussed, not military affairs, which blocked Jiang Gan's mouth. Zhou Yu pretended to be drunk and asked Jiang Gan to sleep together. When Jiang Gan saw that Zhou Yu wouldn't let him talk about surrender, he felt uneasy and couldn't sleep. He sneaked out of bed and saw a letter about Zhou Yu's case. He peeked at the letter, which turned out to be written by Cai Mao and Zhang Yun, and agreed to cooperate with Zhou Yu from the inside to defeat Cao Cao. At this moment, Zhou Yu talked in his sleep and turned over, scaring Jiang Gan to sleep. After a while, suddenly someone wants to see Zhou Yu. Zhou Yu got up and talked to the visitor, pretending to see if Jiang Gan was asleep. Jiang Gan pretended to be asleep, and only listened to Zhou Yu whispering with them, but he couldn't hear clearly. He only heard someone mention Cai Mao and Zhang Yun. So Jiang Gan determined the internal cooperation plan of Cai Mao, Zhang Yun and Zhou Yu. He rushed back to Cao Cao overnight and showed him the forged letters. Cao Cao immediately became furious and killed Cai Mao and Zhang Yun. When Cao Cao calmed down, he realized that Zhou Yu had been played, but he was helpless.
