Tomb raiding has a long history, which has existed since ancient times. For example, the famous Cao Cao alchemy is a captain, and some people say that Cao Cao started from robbing tombs. But a monk's tomb has never been stolen, because Kangxi carved a few words on the monk's tombstone.
These words are "the imperial examination is a legacy, mountains and mountains do not worship ornaments, do not hide treasures." Although it is only 15, the meaning is obvious. This sentence means obeying the wishes of the tomb owner. There are no decent funerary objects in this tomb, let alone gold and silver jewelry.
It is precisely because of these words that grave robbers visited many imperial tombs, but this tomb was not visited. In fact, Kangxi's father Shunzhi was buried in this tomb. Shunzhi died because he loved his concubine, and his heart was dying. He saw through the world of mortals and gave up becoming a monk.
Even if the ancient king became a monk, he could not be cremated like other monks after his death. And although he is a monk, he is also a relative of the country, so the funerary objects in the tomb will definitely make the grave robbers jealous. Kangxi came up with a way to write this line on the tomb.
Grave robbers knew at a glance that the emperor shunzhi couldn't even get the throne, so nine times out of ten there should really be nothing valuable in the tomb. Grave robbers don't want to risk their lives. After all, if you are caught stealing the imperial tomb, you will be exterminated by Jiuzu. So no grave robbers came to visit the mausoleum of Emperor Shunzhi.
