One of the rumors is that someone once entered Liu Bei's tomb. This man is a small county magistrate in the Tang Dynasty named Xu You. It is said that this Xu You is a person who likes to study wonderful events very much, so he also likes to collect some ancient books. Once he got an ancient book about Liu Bei's mausoleum, so he went to find Liu Bei's mausoleum according to the position in the book.
But the location recorded in the book is below his home, so Xu You was very surprised, so he dug a hole in his home and found the entrance. But what's even more shocking is that Xu You actually found a sentence on the wall, which is "Xu You has no hatred or enmity, but opens my grave privately and punishes you for refueling", which makes Xu You feel very horrified.
Moreover, Xu You also found that there was a row of fine print below, which read "I won't die soon", so Xu You immediately ran out and recorded it, so many people were afraid to dig Liu Bei's grave.
There is also a saying that a thief found Liu Bei's tomb. He saw two people playing chess and drinking with others, so the thief also drank wine. The wine was so strong that he was afraid of people. So the thief said that he wanted a treasure, so someone gave him a jade belt. But when the thief woke up the next day, he found that the jade belt in his hand was actually a big snake, so he never dared to steal anything again.
However, these are all rumors. The reason why no one dares to steal Liu Bei's tomb is mainly because Zhuge Liang is a very powerful person in the eyes of outsiders, so many people are afraid that he will die in the tomb and dare not rob the tomb.
