There is a lot of wisdom of the ancients that we can't reach today, because there is no record in the history books, so some anti-corrosion technologies have not been solved so far. In addition to mercury, there is another medicine that can prevent corrosion.
Many archaeologists, when excavating some ancient tombs, will find a lot of potions in the coffins of the dead. These potions can not only preserve the bodies, but also drive away the invasion of snakes, ants and mosquitoes in the ancient tombs.
It's just that ancient tombs used a lot of mercury, and the mausoleum of Qin Shihuang had a lot of mercury. Sima Qian once recorded the scene in the mausoleum of Qin Shihuang in Historical Records. Wherever mercury is described, we pay great attention to it, that is, the mercury in the mausoleum of Qin Shihuang flows all over the corner like mountains and rivers.
Later, when archaeologists surveyed the mausoleum of Qin Shihuang, they also found that there was a lot of mercury underground, so the mausoleum of Qin Shihuang was not opened now, and it was also because the volatilization of a lot of mercury would have a huge impact on the surrounding ecology, so the current technology was not enough to open the mausoleum of Qin Shihuang.
Human society has gradually moved from this feudalism to civilization, so this mode of joint burial has gradually been banned. The reason why Qin Shihuang used so many terracotta warriors and horses to be buried with him was to replace the living. On the surface, Qin Shihuang was a tyrant, but in fact, he also had a good side. Our descendants can only comment on the right and wrong of history, and the specific truth is not clear. Personally, I think Qin Shihuang is a good emperor, because his contribution is obvious to all.
