The Mausoleum of the First Qin Emperor is the first imperial cemetery in the history of China. Its scale is huge and its funerary objects are rich, ranking first among the imperial tombs of past dynasties. The mausoleum of the First Qin Emperor was built from 246 BC to 208 BC, which lasted for 39 years. It is the first royal cemetery with large scale and exquisite design in the history of China. There are two rammed earth walls inside and outside the mausoleum of Qin Shihuang, symbolizing the imperial city and Miyagi in the capital. The mausoleum is located in the south of the inner city, in the shape of a bucket, with a height of 5 1 m and a base circumference of 1.700 m. According to historical records, there are various palaces in the Qinling Mountains, displaying many rare treasures. There are a large number of burial pits and tombs with different shapes and connotations around the Qin Mausoleum, and more than 400 have been proved. The Mausoleum of the First Qin Emperor is the largest imperial mausoleum in the world with the strangest structure and the richest connotation. Terracotta Warriors and Horses of Qin Shihuang are the precious wealth of human culture in the world, which can be compared with Egyptian pyramids and ancient Greek sculptures. 1980 began to be excavated, and it has been included in the national key cultural relics protection units and the world cultural heritage.

According to the latest archaeological data, the actual length of the underground palace in Qinling Mountains is 260m from east to west, north to south 160m, with a total area of 4 1600 m2. The underground palace of Qin Mausoleum is the largest underground palace in Qin and Han Dynasties, and its scale is equivalent to five international football fields. Archaeological drilling further confirmed that this deep and grand underground palace is a vertical cave type. Sima Qian said "going through three springs", while Nine Meanings of Hanshu said "extremely deep". Explain how deep it is to dig to the point where it can no longer be dug, and how deep is the underground palace?

Although this inference is quite different, it is the first time to explore the mystery of Qin Shihuang's mausoleum with modern scientific and technological means. Experts and scholars in the fields of cultural relics, archaeology and geology in China have also done a lot of research and exploration on the depth of the Qin mausoleum underground palace. According to the latest drilling data, the underground palace of Qin Mausoleum is not as deep as people think. The actual depth should be close to the tomb depth of Qin cemetery in Zhiyang No.1. In this way, the actual depth from the pit mouth to the bottom of the underground palace is about 26 meters, and the deepest surface in Qin Dynasty is about 37 meters. It should be said that there will be no big error in this data, which is calculated according to the current exploration results. But whether this is the case or not depends on further verification of archaeological exploration.

At the beginning of the founding of the People's Republic of China, the Soviets tried to dig the mausoleum of Qin Shihuang with manpower and technology, but Chairman Mao refused. At that time, the Soviets said that China could never dig the Mausoleum of Qin Shihuang within 50 years. But from now on, the Soviets at that time will never dig the mausoleum of the First Qin Emperor, which is a technical problem!

The first Qin Shihuang mausoleum contains at least 100 tons of mercury, which is a considerable problem. If 100 tons of mercury leaks, it will cause irreversible losses to Guanzhong area. 100 ton of mercury is only a conservative estimate. If it is leaked out, the consequences can only be described as unimaginable, so the government will definitely not dare to move.

The Second Mausoleum of the First Qin Emperor contains not only things of great historical and cultural value, such as the Empress of Sui Dynasty and Artest bamboo slips, but also the epitaph of the first Qin Emperor himself. Qin history was destroyed before or before the early Han Dynasty, and all records of Qin history, such as Sima Qian and Ban Gu, were a combination of imagination, folk and Warring States history. Qin's manufacturing industry was very developed in ancient China, and even the Terracotta Warriors, known as the eighth wonder, were just the tip of the funerary objects. To what extent is Qin's technology? What does the legendary crossbow firing mechanism look like? Can you see the legendary Daoism? Most importantly, the real life of Qin Shihuang will also be revealed, which will greatly supplement this deficiency in Qin history and let us know more about this ancient dynasty with some mysterious legends and this controversial and charming figure. However, all this must be based on ensuring that the mausoleum of the First Qin Emperor is not destroyed. Now China obviously doesn't have the strength. With the present technology, once opened, all this will be instantly reduced to ashes.

The third mausoleum of Qin Shihuang is exquisitely designed and has many organs. Since ancient times, tombs have ten rooms and nine empty rooms, and most of them have been stolen. However, there is only a stolen cave 250 meters away from the main tomb, and the mercury has not leaked out, which further proves that the mausoleum of the First Qin Emperor has never been stolen for more than 2,000 years. Not only that, in more than 2000 years, there have been more than 20 large earthquakes of magnitude 8 or above in Guanzhong, and the modern detection results have no influence on the mausoleum of the First Qin Emperor. Experts were shocked when fine rammed earth was detected in the upper part of Qin Shihuang's mausoleum, which proved that there were high-rise buildings inside Qin Shihuang's mausoleum, which was very rare. A doctor in Tsinghua studied it for more than 30 years, and only came to the conclusion that it was a pyramid-shaped building. Not only that, the drainage technology of Qin Shihuang's mausoleum is the same as that of Beijing National Grand Theatre. There is also silk, such as just dug out of the tomb, which is very bright and beautiful. It will rot and turn to ashes when it comes into contact with air, so we have to wait until scientific and technological progress. Experts don't even know what Qin Shihuang's mausoleum looks like. Almost every technological progress will produce some new information. China experts have limited knowledge of the Mausoleum of the First Qin Emperor, let alone put forward a complete excavation plan. Only when the technology and excavation scheme are mature will the mausoleum of the First Qin Emperor be opened.
