Let's talk about Cao Cao in the early stage. Cao Cao in the early period was really loyal to the Han Dynasty, which is recognized by most people. Because Cao Cao rose up in the early stage to help the Han family pacify the Yellow Scarf Army and dared to assassinate Dong Zhuo alone. From these two angles, we can see Cao Cao's early loyalty to the Han Dynasty. Of course, this can actually be understood from his life experience, because he was born in a eunuch family, and eunuchs mainly rely on the royal family, so it is inevitable that they will have some different feelings for the royal family. Of course, Cao Cao's loyalty was so prominent because there were few people who could be so loyal at that time. For example, Yuan Shao is a wolf's ambition. On the surface, he actually wants to replace it by saving the Han family. In addition, to see the true history of the Three Kingdoms, we must read The History of the Three Kingdoms, and The Romance of the Three Kingdoms is just a novel.
Let's talk about the late Cao Cao. In fact, Cao Cao in the later period was really not a loyal minister, because after the son of heaven was saved by him, he seemed to be more and more erratic and uncompromising, surpassing the majesty of the son of heaven. Many people will say, didn't Cao Cao fight? Help Han? And never proclaimed himself to death? People who think so are too simple, and the battle for imperial power is extremely cruel, otherwise Xuanwu Gate will not change. Cao Cao hit people? Help Han? Question, one is to really help the Han family, and the other is to find a legal reason to give orders. The reason why you don't call yourself emperor until you die is simple. At that time, although Cao Cao was the most powerful, there were other forces. When the son of heaven was alive, you proclaimed yourself emperor. To be clear is to give others an excuse for you. Some people say that Liu Bei was really a loyal minister of the Han Dynasty, but Liu Bei was a hypocrite in the Three Kingdoms, and the emperor proclaimed himself as soon as he died.
Generally speaking, as for Cao Cao's loyalty, I can only think that he was really loyal to the Han Dynasty in the early stage, but he is not sure in the later stage, but certainly not 100% loyal to the Han Dynasty.
