Ancient China has a long history, both brilliant and dazzling ancient culture, but also has a backward and cruel feudal tradition, the burial system is one of them, the Ancient Chinese people believe that after death, the soul is born in another world, and the tomb is the residence of the tomb owner in another world.
Therefore, as early as the Shang Dynasty, the burial system began to be implemented, archaeologists found in Anyang, Henan Province, slave owners tomb group found, usually a tomb has dozens of people buried, merchants believe that slaves are buried, after death can also be driven and enslaved by the master, dog bones are placed next to the bones of slaves who raise dogs, and there are cars and horses next to the slaves who drive specially.
After the Shang Dynasty, the Spring and Autumn Warring States and then the Qin Dynasty followed the tradition of the past, although the Qin Dynasty was followed by a feudal dynasty, but the emperor died, still had to accompany many harem concubines and servants. During the Spring and Autumn Period and the Warring States Period, not only the Son of Heaven had to be martyred when he died, but also the more powerful princes and noble ministers who died were also martyred.
The "Mozi Festival Burial" chapter says: The Son of Heaven kills martyrs, many hundreds, and the widows are dozens; the general doctor kills martyrs, the many are dozens, and the widows are counted.
In 210 BC, after the death of Qin Shi Huang, Qin II Hu Hai ordered that all those who had no children in Qin Shi Huang's harem would die, because many harem concubines did not give birth to qin shi huang, so many people died.
Not only was he a harem servant, But Hu Hai also put his abacus on the craftsmen who built the tombs of Qin Shi Huang, who had built luxurious and extravagant mausoleums for himself long before his death, and also placed a large amount of gold and silver jewelry after his death in order to be brought to another world after death.
Qin II Hu Hai was afraid of those who built the qin shi huang mausoleum underground palace, knew the entrance to the underground palace, and then colluded with others to steal the tomb, and at the same time, according to the superstitious tradition at that time, hoped that Qin Shi Huang would have a very large number of servants in another world to enjoy, so he decided to leave some skilled craftsmen who made the imperial tomb in the underground palace for Qin Shi Huang to be buried.
The "History of Qin Benji" records: "Burial is under the ground, or the craftsman is said to be an opportunity, Zang (that is, slaves) are known, and Zang is heavy and leaked." After the big event, Zang has closed the envy in the middle, the envy of the outside, the closed craftsman Zang, and there is no comeback. ”
That is to say, Qin locked the craftsmen in the underground palace and could not come out, in fact, when Qin Shi Huang forcibly recruited those skilled craftsmen to build the underground palace for himself, these craftsmen should also see something, with the prevalence of the martyrdom system at that time, coupled with the tyranny of Qin Shi Huang, he may not have a good end in the future.
These people cleverly left a hand for themselves, building a secret passage to facilitate future escapes, and because the design was so hidden, the overseers could not actually see it. This mechanism is also called "wooden bolt top door", usually leaving only a gap.
But if the emperor killed these craftsmen, when the tomb was closed, the craftsmen would be able to use this gap to open a secret passage to the outside world. Of course, this is a folk wild history rumor, but the burial system continued until the Qing Dynasty, and Sun Dianying found such a passage when he stole the tomb, presumably prepared by craftsmen in case of accidents.
People can deal with the situation of closing the tomb door, but some cruel emperors are not so humane, and they are likely to kill the people who want to be martyred before the first emperor is buried, so there is no way to escape.
