In fact, the bad habit of robbing tombs has a long history. The motive of most grave robbers is to steal property, while others are for revenge or the items in the tomb have special functions. The reason why people hate digging graves is related to our traditional views on life and death, morality and values. Ancestor's tomb represents a memorial, a sustenance and a comfort for future generations. It represents the burial of ancestors and is of great significance. Protecting tombs has become our tacit moral standard and code of conduct. Therefore, basically every dynasty has formulated a severe punishment system to curb grave robbery.
Digging graves is not a human behavior from the beginning, but a derivative of the development of human civilization to a certain extent. After all, the funerary objects at the beginning of the tomb are just some daily necessities used by ancestors to express their commemoration of the deceased. Later, with the improvement of living standards and the concentration of power, the status of princes became prominent, and tombs became more and more precious, which naturally made some grave robbers ready to move. It was not until everyone found that the grave robbery industry was profitable that they followed suit.
Therefore, the past dynasties can only be curbed by some severe punishment systems.
