Cao Cao stole the mausoleum of Liu Wu, Liang Xiaowang in Han Dynasty, and obtained a large number of gold, silver and jewels as military assets. Liu Wu, Liang Xiaowang of the Han Dynasty, was the younger brother of Liu Qi, Emperor Wu of the Han Dynasty, and their mothers were both famous Dou Taihou. Just like ordinary families, parents always prefer their youngest son, and Dou Taihou is no exception. She also cherishes her youngest son more, and even wants Liu Qi to pass the throne to Liu Wu instead of Liu Qi's own son.

Liu Qi has deep feelings for Liu Wu. At a banquet, he even said publicly that he would pass the throne to Liu Wu in one hundred years. Liu Wu, who was loved by his mother and brother, was not satisfied. He really wanted to ascend the throne. Later, he even sent people to assassinate ministers in North Korea who disagreed with him. After this incident was discovered by Liu Qi, he was ordered to leave the capital.

Later, Liu Wu wrote that he would come back to serve Dou Taihou, but Liu Qi refused, so he was depressed, seriously ill and finally died. Liu Qi blamed himself for this incident, and Dou Taihou was so sad that Liu Qi not only divided Liu Wu's fief beams into five countries, but also gave them to Li Jue's five sons, and gave most of the treasures in the state treasury to Liu Wu for burial.

Because Liu Wu once made great contributions to the rebellion of the Seven Kings, and Liu Wu plundered a lot of property in the rebellion of the Seven Kings, plus what Dou Taihou and Liu Qi gave him at ordinary times, he buried all these treasures for himself. There are still 400,000 Jin of gold in the family that can't be buried, let alone the treasure buried with him. Its value is definitely far more than this 400,000 Jin of gold, so when Cao Cao has no military expenditure, the first thing that comes to mind is this extremely extravagant and doting Liang Xiaowang. Sure enough, the funerary objects in Liang Xiaowang's tomb were enough for his army to eat and drink for several years.
