In ancient feudal society, because of the low level of social productivity, so the ancients could not understand some natural phenomena, there will be a lot of strange and chaotic ideas, and there is also a great importance to posthumous things, such as the funeral after the death of the ancients is very solemn, and will accompany the burial of many precious treasures, the emperor and concubines not only have a lot of valuable funerary goods when they are buried, but also specially block the anus.
Since ancient times, the wind of thick burial in the mainland is prevalent, which is not entirely superstitious, which also has mourning and blessings for the deceased, and the concubines are plugged in the anus before burial, there are also scientific reasons, because in ancient times, they are generally buried, and the technology of preserving the remains is very backward, so blocking the anus of the concubines is to allow the remains to be preserved for a longer time, and now after the excavation of many ancient tombs, experts have found that many of the concubines' remains are vivid, in fact, it is because of this reason.
After death, people will discharge a lot of fluids in the body, and the hot and humid environment will accelerate the decay of the body, and there are many bacteria and viruses in the body fluids, so the ancients decided to block the nine tricks of the human body, so that they can prevent the flow of body fluids, which naturally includes the anus, at that time in order to choose to block the nine tricks of the tool headache for a long time, and finally the ancients decided to use jade to block the nine tips.
Ge Hong of the Western Jin Dynasty wrote in "Baopuzi": "If the gold and jade are in the Nine Tricks, the dead are immortal." This also means that the ancients believed that doing so could make the body immortal, and jade could preserve people's souls, so blocking people's nine tricks can save people's souls, so that they can avoid the six reincarnations and continue to enjoy the blessings and wealth of their lives, of course, there are some superstitious colors, but this is indeed scientifically based.
