Why did ancient emperors like to bury boys and girls alive with mercury? What's the secret here?

Speaking of human sacrifices in ancient times, funerary objects can be said to have everything, because tombs were highly valued in ancient times, especially in emperors' homes. The burial place must not only be a treasure trove of geomantic omen, but also be built properly, and the anti-theft measures should be done well, so as not to give the grave robbers an opportunity. This burial object is naturally indispensable.

However, there was a very cruel martyrdom system in ancient times. Although it was abolished after Qin Shihuang came to power in the later period and replaced by Terracotta Warriors, many dynasties still followed the system of human sacrifice, and that's it. It is even more cruel to let boys and girls die for this, which is outrageous. Then why?

There is a main reason for the ancient human martyrdom system. I hope the people buried with me can take care of the dead. The higher their status, the more people die. The reason why virgins are buried is because the ancients believed in the existence of immortals, and every mortal has a little fairy spirit.

How cruel it is! These children were brutally killed in dark graves before they felt the beauty of the world. However, this dehumanizing system has been unanimously recognized by emperors of all dynasties, especially the Ming Dynasty. When Zhu Yuanzhang died, Zhu Jun? Noon? Su Meng made an appointment with the drought man. Once, Changxing? Swing your arm? Lun you? Tomb? Awe? Jia? Hey? Bayanman? Dirt? Hey? Children have a nice name-"Chaotian Girl"
