According to "Notes on Water Classics", when Qin Shihuang chose the mausoleum site, he deliberately chose the northeast of Lishan Mountain. Originally, the river flowed to the northeast, but Qin Shihuang built a dam, which was more than 1000 meters long, 40 meters wide and 70 meters high, and abruptly turned the river to the northwest. This dam is now the location of Wuling.
Because of man-made interference with the direction of the river, a huge pool was formed next to the mausoleum of Qin Shihuang, which is what the ancients called a fish pond. Some scholars speculate that besides geomantic considerations, Qin Shihuang also had an important purpose, that is, to let water provide power for the machinery in Qin Shihuang's mausoleum.
The role of mercury in the mausoleum of Qin Shihuang;
The100t mercury in the Qin Shihuang Mausoleum has anti-theft function. Because mercury is a toxic metal, it is very toxic, and it can also volatilize into the air at room temperature to make people poisoned. There is a lot of mercury protection in Qin Shihuang's mausoleum, which has stopped a batch of grave robbers. This mausoleum has been preserved for more than 2000 years.
Mercury has a long-standing anti-corrosion function, and Qi Huangong's mausoleum was once protected by mercury. Using mercury can not only slow down the decay of your body, but also protect treasures.
