Speaking of the emperor's mausoleum, I am afraid that no mausoleum in China can compare with the mausoleum of Qin Shi Huang - Qin Shi Huang Mausoleum (also known as Lishan Mausoleum). This mausoleum is more than 2,200 years old, the main burial chamber has never been excavated, and the various legends about it have also cast a mysterious color on it. No one knows.

The Mausoleum of Qin Shi Huang is bordered by Lishan Mountain in the south and the Weishui River in the north, covering an area of 56 square kilometers, equivalent to the area of 78 Forbidden Cities, which can be described as very huge. Lishan Mountain is a branch of the northern foothills of the Qinling Mountains, stretching about 25 kilometers from east to west, about 7 kilometers wide from north to south, and about 1,000 meters above sea level.
Li Bai has a poem cloud "700,000 prisoners, from the soil Li Shan Kuma", this sentence well reflects the scale of the construction of the Mausoleum of the First Emperor of Qin, the "History" records that The Minister Li Si is the designer of the mausoleum, the Shaofu LingZhang Handan is the director of the work, the mausoleum was built when 720,000 manpower was collected, at most close to 800,000 people, equivalent to the construction of the Pyramid of Khufu (the largest pyramid in ancient Egypt) 8 times the number of people, before and after nearly 40 years, the construction time is also twice the pyramid of Khufu, from the perspective of manpower and construction time, The amount of work is equivalent to 16 times that of the Pyramid of Khufu, which shows how huge this project is.
The most mysterious of the Qin Shi Huang Mausoleum is the imperial tomb of the underground palace, China's current stage of the first comprehensive archaeological survey of the Qin Shi Huang Mausoleum began in 1962, when it was considered that the grand scale of the underground palace is located on the top platform of the sealing mound and below it, researchers also found that there is a very thick circle of fine rammed earth walls around the tomb under the sealing mound, that is, the so-called palace wall. It has been verified that the palace wall is about 168 meters long from east to west, 141 meters from north to south, 16 meters wide from the south wall and 22 meters wide from the north wall. The top of the palace wall was even much higher than the ground of the Qin Dynasty at that time, and down to 33 meters below the current sealed soil, and on the inside of this earthen wall, researchers found a stone palace wall.
The "Chronicle of History" also records that the Qinling underground palace "with mercury as a hundred rivers and seas", physical detection proves that there is indeed a significant mercury anomaly in the underground palace, which is also a means for Qin Shi Huang to protect the mausoleum, because the mercury gas pervaded in the underground palace can not only keep the buried corpses and burial goods for a long time without decay, but also let those who rush into the underground palace inhale poisonous gas to die, because mercury is a highly toxic substance, it is also easy to volatilize into gas, and a large amount of inhalation can lead to death, which can make tomb robbers prohibitive. In addition, archaeologists have also detected the existence of stone burial chambers inside.
The latest archaeological exploration shows that the Qinling Underground Palace is actually 260 meters long from east to west, 160 meters from north to south, with a total area of 41,600 square meters, the scale is equivalent to 5 standard football fields, the shallow distance from the ground is about 26 meters, and the qin Dynasty sealing soil layer is 37 meters.
The above situation and data also tell us how difficult it is to excavate the mausoleum of Qin Shi Huang. First of all, the scale of the Mausoleum of The First Emperor of Qin is very huge, a mausoleum that seven or eight hundred thousand people spent 40 years to build, of course, is not easy to be opened, and how many traps are there in the mausoleum? No one knows, but measuring Qin Shi Huang's defensive heart, this aspect is certainly indispensable, there is mercury poison gas in Qin Shi Huang's underground palace, tomb robbers are greedy for money, and do not dare to give their lives to enter, and the depth of the qin shi huang mausoleum is also breathtaking, digging down 30 meters deep is not so easy, ancient wells are not so deep, so from various circumstances, it is not so easy to excavate the qin shi huang mausoleum.
So is it really impossible to excavate the Mausoleum of the First Emperor of Qin? Of course not, under the power of modern construction machinery and explosives, the mausoleum of Qin Shi Huang is no matter how big and strong, in January can also be dug up to the sky, this only needs a large demolition team can do, but not to excavate the tomb of the deceased is a universal value of mankind, not to mention that Qin Shi Huang is an emperor throughout the ages, although he also has some mistakes, but he established China's first feudal unified country, and unified coins, writing, weights and measures, books with the same text, car with the return, the implementation of the county system, Various measures have made outstanding contributions to the unification of China's culture and political system, so it itself has great commemorative significance, and what he left behind has become a precious cultural relic, so of course, the Mausoleum of Qin Shi Huang, where his body was buried, has become a cultural relics unit that cannot be changed at will. Protecting this mausoleum is also a respect for Qin Shi Huang, for history, and for the universal values of mankind, so the Qin Shi Huang Mausoleum cannot be excavated, of course, we cannot just want to see the real appearance of the Qin Shi Huang Mausoleum and the treasures inside.
