First of all, in his legacy and legacy, Cao Cao really emphasized the simplicity of funeral, demanding that the mausoleum be "not sealed, not planted with trees" and "without treasures and jewels". But what he asked for was not to dig Liang Xiaowang's tomb for fear of retaliation, but because grave robbing activities were rampant for a long time before Wei and Jin Dynasties, and grave robbing was the focus of grave robbers.
Cao Pi, Emperor Wen of Wei, once said: "Since ancient times and today, there is no immortal country and no grave to dig. Since the chaos, all the tombs in the Han Dynasty have been excavated, and even jade boxes and bones have been burned, which is a punishment of burning. Is it not painful? " Some people also say that "the Chinese emperor does not send it, and Baling has nothing to ask for; The excavation of Guangwu, the original tomb sealed the tree. " Only those tombs that are too ostentatious will be stolen, and low-key tombs are generally no problem. Even the Empress Vendeutsche once said, "Since the rebellion, all graves have been excavated, and they are all buried in a thick way".
It can be seen that the rulers of Cao Wei are still cautious about "thick burial". Therefore, the rulers of Cao Wei advocated simple funeral and were afraid of grave robbers who stole money, instead of "revenge for grave robbery". They think that as long as valuables are kept, his mausoleum will not be "visited" by future generations.
Let me say again why simple funerals don't aim at "revenge for robbing a tomb"
The first reason is that he dug the tomb of Liang Xiaowang in the Western Han Dynasty. Although the orthodoxy inherited by the Eastern Han Dynasty came from the Western Han Dynasty, there was an unpleasant history between Liang Xiaowang and the royal family in the Western Han Dynasty, so it didn't touch the ruling class in the Eastern Han Dynasty much, nor did it cause grave robbery revenge.
The second reason is that Cao Cao did not hide the location of his tomb, and the location was very clear, and there was no "seventy-two suspected graves". Later, archaeologists also proved that the so-called "seventy-two suspected tombs" were tombs of the Northern Dynasties, and they were not seventy-two tombs, but tombs of 134. Moreover, in the Tang Dynasty, Emperor Taizong also paid homage to Cao Cao's tomb, which shows that the location of Cao Cao's tomb is no secret. Not to mention preventing revenge from grave robbery.
The third reason, in the history before Wei and Jin Dynasties, grave robbery was rampant. Far away, let's say that during the Qin and Han Dynasties, Xiang Yu entered Xianyang City and ransacked the mausoleum of Qin State. It is estimated that Xiang Yu should be the first grave robber with a great army in the history of China, for the purpose of plundering wealth. Shortly after the death of Emperor Wu of the Han Dynasty, people began to rob tombs in exchange for wealth. During the Han Dynasty, the Red Eyebrow Army led by Fan Chong, a native of Langya, robbed the royal tombs of the Western Han Dynasty twice on a large scale.
At the end of the Eastern Han Dynasty, after Dong Zhuo went to Beijing, he also excavated the tombs of emperors, such as the mausoleum of Emperor Ling. This is just a record, and there are many things that have not been recorded. Cao Cao's inspiration comes from "the wisdom of predecessors". It's not just Cao Cao. A few years later, Sun Quan, the owner of Wu, finally dug up Rui's tomb and took out the coffin to make wood for the Sun Jian Temple in order to repair the Sun Jian Temple. Even the bamboo annals and the biography of Mu, which we know, were discovered by grave robbers in the Western Jin Dynasty. It can be seen that it was a common "routine operation" to dig graves to subsidize other uses when resources were scarce at that time. It is estimated that Cao Cao would not have thought of revenge at that time.
To sum up, Cao Cao was really afraid of being robbed, but it was not directly related to Cao Cao setting up a captain to dig Liang Xiaowang's mausoleum. That is to say, when Cao Cao digs Liang Xiaowang's mausoleum, he won't worry that his mausoleum will be stolen.
