What actions of Cao Cao make you remember?

In the fifth year of Jian 'an in the Eastern Han Dynasty (200), Cao Cao's whole army defeated Yuan Shao's army in Guandu (now Zhongmoujing, Henan). At the end of the Eastern Han Dynasty, strongmen became independent and fought in the Central Plains. At that time, Yuan Shao owned four states: Hebei, Qinghai, Youzhou and Hebei. Relying on his ample food, he plotted to destroy Cao Cao in Yanzhou and Henan. In January of the fifth year of Jian 'an, the decline rate of elite soldiers was 654.38+ 10,000. Before that, Cao Cao had defeated Liu Bei, who was allied with Shao, and moved to Guandu, which was easy to defend but difficult to attack. In April, Cao Cao defeated Yan Liang and defeated the army in Baima (now hua county, Henan) by a diversion. Shao was defeated in the first battle, and his spirit was frustrated, so he divided his troops and attacked the camp. The two armies fought in Guandu for several months. At the same time, Cao Cao wanted to defend Xuchang (now Xu Changdong, Henan) for lack of soldiers and food. Yu Xun, the counselor, believes that Cao Jun will defeat the strong with weakness, and at this time, withdrawing troops will take advantage of it; On the other hand, the defeated army underestimates the enemy and there is internal discord. After a long stalemate, it will definitely change, and it will be a surprise victory. Cao Cao listened to his words, sent troops to attack and burned the commissary car; He also led an elite army of 5,000 people to attack the grain depot in Wu Chao (now Henan), wiped out the defeated army and burned all the stored grain. When the news came, Shao and others were shaken and surrendered. Cao Cao took the opportunity to attack on all fronts and annihilated more than 70,000 enemy troops. Only 800 father and son fled north. The battle of Guandu laid the foundation for Cao Cao to unify the north, and Shao's decline never recovered. The battle of Guandu is a famous example in the history of ancient wars in China.

Second, watch plums quench your thirst.

On the way to March, Cao Cao got lost in the water, and the soldiers were very thirsty, so he ordered: "There is a piece of Merlin in front, which is rich in fruit, sour and sweet, and can quench their thirst." Hearing this, the soldiers all shed saliva in their mouths. (Cao Cao) Take this opportunity to lead the troops to the place where there is water ahead.

Third, cooking wine on heroes.

In the Three Kingdoms, Dong Cheng made an appointment with Liu Bei and others to form an alliance with Cao. Liu Bei was afraid of Cao Cao's suspicion and watered the beans every day. When Cao Cao heard about it, he set up a monkey: set up a plum and cook wine in a bottle. The two sat opposite each other and drank heartily. Talk about heroes in the world. Liu Bei was shocked when Cao Cao said that "all heroes in the world only listen to the king". The sunny weather suddenly thundered. Liu Bei concealed Cao Cao's doubts by being timid and afraid of thunder, and asked him to suppress Yuan Shu. Then Guan Yu and Zhang Fei arrived to get away. At that time, Cao Cao tentatively gave a banquet, while Liu Bei was fearful, hoping not to arouse Cao Cao's suspicion.
