Cao Cao is well known, but in fact, Cao Cao should be: holding the son of heaven to make him disobedient. Later, it was said by the world: holding the emperor to make the princes. The real ones should be them: Zhao Gao (Qin), Dong Zhuo (Three Kingdoms), Yuan Shu (Three Kingdoms), Yan Song (Ming) and Cixi (Qing). Background information of Cao Cao: Go to Youku Video to see Yi Zhongtian's Three Kingdoms, and he is the real Cao Cao! Chu Chu's biography of Yuan Shaochuan: "Today, the city is rough, the soldiers are strong and the soldiers are attached, and the west welcomes the coach, that is, the palace capital, relying on the emperor to make the princes, and storing horses to discuss the court. Who can resist it?" Xian Di said in the Spring and Autumn Period: Yuan Shao rebelled against Yi Gong and said, "Tian Feng sent Shao to attack Xu early. If you take the emperor to make princes, the whole world can decide what to do." Gong is the solution to embroidery. Cao Cao is much more brilliant. Cao Cao doesn't change emperors. He uses this ready-made emperor, and he worships it civilly, using the emperor's card to order the world and call on the princes. This is what we usually call "holding the emperor to make the princes". In fact, this statement can be discussed. Cao Cao himself and the people in Cao Cao Group have never said that "the emperor is held to make the princes". The saying "hold the emperor to make the vassal" is said by Cao Cao. For example, Zhuge Liang said this. His saying is "hold the emperor to make the vassal", but the meaning is the same. That is to say, Cao Cao's enemy said that he was "holding the emperor to make the princes", so his words are not very reliable! So, has anyone ever said that "the emperor is used to make the princes"? Yes, who is it? Ju Shou, Yuan Shao's counselor, is called "the emperor is held by the emperor, and the livestock and horses can't win the court", but other counselors under Yuan Shao don't agree, saying that the emperor is a waste now. What are you doing with such a waste? Do you worship him or not? Are you asking him or not? Then you must worship and ask for instructions. I will ask the emperor for instructions on major issues and minor issues after I get him here now. What if the emperor's opinions are different from ours? Do I listen to him or not? I listen to him, which makes us look insignificant. If I don't listen to him, isn't it illegal for me? Forget it. Forget it. What does Yuan Shao think? Yuan Shao thought that Dong Zhuo helped the current emperor, and I didn't do it when Dong Zhuo wanted to abolish the emperor. Now I'm going to worship him again. Didn't I slap myself? Of course, I can't help the emperor I advocate now. That emperor has been murdered by Dong Zhuo. Forget it. Then when Yuan Shao hesitated about this matter, Cao Cao took the lead. In 196 AD, Emperor Xian of Han Dynasty, who was abducted to Xi 'an by Dong Zhuo, went through all kinds of hardships and returned to Luoyang, the capital at that time. At this time, Luoyang was in ruins and dilapidated. In Luoyang, the emperors and officials even lived like beggars. After learning this news, Cao Cao decisively adopted the advice of Mao Jie, a counselor, to "serve the son of heaven so as not to be a minister" and tried his best to take the emperor from Luoyang to Xu County, his base area.
