1. Say Cao Cao, and Cao Cao will come. Cao Cao is known as a capable minister in governing the world and a hero in troubled times. He was originally a eunuch, but through his continuous efforts and taking advantage of the troubled times, he successfully gained the advantage of holding the emperor hostage and commanding the princes. If we talk about the Three Kingdoms period, who received the most attention was undoubtedly Cao Cao. However, before he established Emperor Xian, Cao Cao's power was limited to the Yanzhou area. Therefore, when he led his army to attack Xuzhou, Lu Bu, who had no foothold at the time, took the opportunity to attack his Yanzhou Puyang. After hearing the news, Cao Cao immediately returned to his army to help. Unfortunately, Lu Bu was very brave. At the beginning, Cao Cao did not gain the advantage and even almost lost his life. However, when Lu Bu was chasing Cao Cao at night, Cao Cao happened to be met by him. As the saying goes, say Cao Cao, and Cao Cao will come. It means it's quite a coincidence. However, Lu Bu did not realize that the person in front of him was Cao Cao. He only regarded him as a soldier, and ultimately missed the opportunity to capture Cao Cao. So that later generations added another sentence after "Speak of Cao Cao, and Cao Cao will arrive": "It would be funny if you missed it in person." Come and tell Lu Bu's stupidity and regrets.

2. Crouching dragon and phoenix, one of them can bring peace to the world. When Liu Bei defected to Liu Biao in Jingzhou, in order to seek help from capable people in the world, he visited famous people in Nanyang. And just after the Lu horse he rode crossed Tanxi River, he happened to meet the local Mr. Shui Jing, Sima Hui. Although Sima Hui is a powerful person, he has already seen through the world, so he does not want to get involved in politics. But in order to show his approval of Liu Bei, he still recommended Zhuge Liang and others to him. He also said the famous saying "Crouching dragon and phoenix chick, one of them can bring peace to the world". Later, as Sima Hui said, Liu Bei successfully obtained the assistance of Mr. Wolong Zhuge Liang and Fengxiao Pang Tong, and successively obtained the land of Jingzhou and Xichuan, becoming a hero who could fight against his powerful enemy Cao Cao. However, when he captured Xichuan, Fengchu Pang Tong was killed by an arrow early. Later, Zhuge Liang made six trips to Qishan but still failed to conquer the Central Plains and revive the Han Dynasty. Later, Sima Hui then told others: "Kong Ming had his talent, but it was not at the right time!" He detailed the regrets of Kong Ming's life.

3. If there is beauty, how can there be brightness? Zhou Yu, the governor of Soochow. This man was both civil and military, elegant and handsome, and was one of the few handsome men during the Three Kingdoms period. At that time, Cao Cao pacified the north, annexed Jingzhou, and personally led hundreds of thousands of troops southward, intending to capture the land of Soochow. Zhou Yu urged Sun Quan to resist, and led tens of thousands of Sun Quan and Liu allied troops to fight against Cao's army in Chibi. In the end, he successfully used the bitter flesh and fire tactics to defeat Cao Cao and completely ruined his dream of quick unification.

4. Having children should be like Sun Zhongmou. After Cao Cao was defeated in Chibi, after years of recuperation, he continued to lead his army south to prepare to attack Soochow. At that time, Cao's army was confronting Liu Bei on the western front and had no progress for a long time, so he prepared to quickly take over the eastern front. Reluctantly, Soochow took advantage of the natural chasm of the Yangtze River and several years of recuperation, and its power reached a point where it was not easy to defeat. As a result, Cao Cao's army confronted Sun Quan's troops at Ruxukou. At that time, Cao Cao climbed up and looked into the distance, and happened to see Sun Quan in the opponent's army. He saw him sitting calmly and looking like a king. Nai sighed: "I should give birth to a son like Sun Zhongmou!" to express his recognition of Sun Quan's ability and his expectations for his descendants. Of course, his descendants Cao Pi and Cao _ are also very capable, and they do not even belong to Sun Quan. However, they both had no choice but to die young, which allowed Sima Yi to take advantage of the opportunity and seize Cao Wei's empire. It left the Cao family with infinite regrets.

5. Sima Zhao’s heart is known to everyone on the road. Two years after the Gaopingling coup, Sima Yi died. The Sima family's power was inherited by Sima Shi. However, the Sima family, who had just taken control of Cao Wei's political situation, had to face many dissatisfied old officials of the Cao family. In the end, Sima Division was unfortunately seriously injured and died while pacifying the war in the south. As a result, the power of the Sima family fell into the hands of Sima Zhao again. Compared with Sima Shi, Sima Zhao's city was even more profound. During his time in power, he not only successfully destroyed the Shu Han and consolidated the family's power, but also successfully promoted to the title of King of Jin. It has reached the power of Cao Cao back then. However, at this time, the puppet emperor Cao Mao, who was unwilling to lose power, openly led his army to attack Sima Zhao. And shouted the indignant words "Sima Zhao's heart is known to everyone passing by". You know, although everyone in the world knew that Sima Zhao wanted to usurp power, Cao Mao was the only one who dared to shout it out in public! Just the act of shouting these words was so heroic.
