Why can't Qin Shihuang's tomb be dug?
Technical problems.
It is easy to dig out, but difficult to store. Like Mawangdui's tomb, the contents are dug out and turn into fly ash at the sight of air.
I heard that Japan wants to help us dig, but the condition is that we need three things after digging. Qin Shihuang put it on his head, held it in his hand and put it in his mouth. Our country disagrees. Mainly, two ancient pirate caves have been found in several aspects, but they are only more than one meter deep. The reason is that after the first emperor was buried, a large amount of mercury (mercury) spilled within one kilometer of Fiona Fang, which was highly radioactive. Ancient people lost their hair and teeth when they dug one meter deep without chemical protection measures, and then they became warped when they dug again. Of course, they won't dig any more! In addition, the size of the first emperor's tomb was adjusted. According to the location distribution of China at that time, an international standard football field was filled with a lot of mercury, which was also dead! And this football field was built of mud and rice slurry with the most advanced technology at that time. I use vernacular here: after the tomb wall was built, the soldiers with the strongest crossbow in Daqin stood at 100 step and fired at the wall. If the arrow arrives but doesn't drop the soil, it means that it can't go in or drop the soil on the surface. Even if it passes the customs, it will be pushed away, and the workers who manage the wall will be killed and replaced, which can never be compared with the cement now. At the same time, it is recorded that the tomb of the first emperor is under the tomb of Jiuquan, which actually means that you dare not go at this depth! Hey hey! There is too much mercury on the ground, and there is no shelter for one kilometer of trees in Fiona Fang, so it is no problem to be caught at night and during the day! But you have to wear advanced chemical protective clothing first, but if you can afford it, you should not want to be a grave robber! Hehe ~' There is also a legend that Zhao Gao used salted fish to cover up the rotten smell. Because the first emperor died on the road, the tomb of the first emperor was a very creative ancient man drifting along the mercury! There are countless treasures inside. It is said that there is nothing wrong with using the Great Night Pearl as the sun and moon organ, but there are indeed many workers buried with them, just to prevent them from leaking secrets, and they are buried alive under a deep passage from the outside of the main tomb of the first emperor to the outer wall, just like the entrance of the Egyptian pyramid! Our country has long proved that it just lacks the preservation technology of unearthed cultural relics! There are many intact cultural relics in it. If we can't protect them, we can only let our generation see them! Future generations can only look at photos! ! ! !
Why can't Qin Huangling open it?
The mysterious and charming underground palace of Qin Shihuang's mausoleum has always attracted the attention of the world. Not long ago, Mr. Zhang Wuchang calculated an economic account for the opening of the underground palace of Qin Mausoleum. He said; "If the Mausoleum of the First Qin Emperor is opened, the annual ticket revenue will reach 2.5 billion yuan." This is a great growth point. Subsequently, it triggered a big discussion on "excavating the underground palace of the Qin tombs as soon as possible". After searching, the reasons for advocating the excavation of the Qin Mausoleum underground palace are as follows:
On the one hand, the theory of "waste of resources" holds that if the Qin Mausoleum is not excavated, it is just a pile of loess, which is also a huge waste of tourism resources. Only when it is open can it be valuable and contribute to society. If it has never been opened, it is worthless.
The second is the theory of "encouraging pride", which holds that the excavation of the Qin Mausoleum can arouse people's attention, promote the participation of the whole people, unite people's hearts, and then arouse people's enthusiasm and concern for Chinese culture. At the same time, it can also attract world-class experts and scientific research institutions to make suggestions, which is of great benefit to promoting China culture to the whole world and cultivating China people's enthusiasm and national pride in their own culture.
The third is the theory of "confirming documents", which holds that Sima Qian's Historical Records records the underground palace of the Qin tombs, for example, the Palace Museum is full of strange things and monsters; There are astronomy in the tomb and geography in the tomb, and mercury is a hundred rivers and seas, mechanically instilled; Let craftsmen make crossbows and bows to prevent grave robbers, and so on. Open the underground palace and confirm the credibility and accuracy of the records in Historical Records.
According to the theory of "effective protection", if the Qin Mausoleum is not excavated as early as possible, the cultural relics in the underground palace will only rot gradually, because it is common for the underground palace to be flooded, and there are other unforeseen and unknown factors. So how to protect it? Only excavation can effectively protect it.
According to the theory of "excavation by stages", opening the mausoleum of Qin Shihuang is not entirely a technical problem. Who can tell what kind of technology is needed after opening? Only by gradually excavating the Qin Mausoleum in stages can we find problems at any time, study necessary protection technologies at any time, and achieve "targeted".
According to the theory of "learning from foreigners", foreign countries have the experience of stealing tombs, which is worth learning. Some also take the excavation of the Egyptian pyramids as a successful model, which not only promoted civilization, but also attracted a large number of tourists and achieved considerable economic benefits. The protection, development and utilization of cultural relics go hand in hand and complement each other.
According to the theory of "satisfying public opinion", the First Imperial Tomb is an underground "kingdom" full of magical colors. The deep underground palace is full of mystery. The shape and internal structure of the underground palace are still unclear, which has aroused the speculation and reverie of many scholars for thousands of years. Now people have a very strong motivation and desire, so we have to consider this kind of public opinion.
Faced with all these arguments, archaeologists say, is the mausoleum of the First Qin Emperor open? What time does it open? Not determined by the wishes of economists or some people. Archaeology, after all, is a highly professional industry, and archaeological excavation is also a very complicated project.
Researcher Duan Qingbo, the captain of the Qin Mausoleum Archaeological Team, said: "In the current environment, there is no reason to constitute an excuse for stealing the mausoleum of the First Qin Emperor. It is an illusion to promote the local economic development by excavating the emperor's mausoleum and promoting tourism with cultural relics, which is a way to kill the goose that lays the golden egg. I may not see the secret of the underground palace in my life, but I am still willing to devote my life to the archaeological cause of the First Qin Emperor! "
Duan Qingbo also said that in addition to technical deficiencies, social mentality must also be considered. At present, the archaeological technology in China is still immature. Who can guarantee that the unearthed cultural relics are foolproof? If we contemporary people do not follow the objective laws and only try to explore the mausoleum of the First Qin Emperor by impulse, then future generations will not praise our wisdom, but may blame us for our foolish behavior that leads to endless troubles because of quick success and instant benefit.
Why can't the mausoleum of Qin Shihuang be opened?
Why can't the eternal mystery of the first imperial tomb be solved?
Although Jackie Chan, a movie superstar, imagines the mausoleum of the First Qin Emperor as a weightless world in his new film Myth, the mausoleum of the First Qin Emperor is still an unknown "myth" to the world, and archaeologists believe that it is still the safest way to let it sleep underground.
"Excavation sometimes means destruction," said Mitchell Peset, president of the International Council of Monuments and Sites, who is attending the 15 General Assembly of the International Council of Monuments and Sites in Xi. "Qin Shihuang's underground palace is too big. After digging, people can't protect it. "
"If this underground palace is an earth structure-just like the Terracotta Warriors and Horses of Qin Shihuang's underground army, it will be completely destroyed after several months of excavation. At present, there is no reliable technology in the world that can protect the soil structure like the Terracotta Warriors. Any excavation can't be for fun or curiosity. " Peset said.
In Peset's view, although the terracotta warriors and horses have been burned into pottery, they are still fragile compared with the western stone carvings.
National Cultural Heritage Administration has not advocated active excavation. According to the relevant provisions of the Law of People's Republic of China (PRC) on the Protection of Cultural Relics, archaeologists are allowed to carry out protective excavation of such sites unless they encounter some natural disasters, grave robberies or major projects related to the national economy and people's livelihood.
Zhang Bai, deputy director of National Cultural Heritage Administration, said: "These cultural relics have been buried in the tomb for more than 1000 years, and they have reached a state of balance. If these cultural relics are excavated and exposed to sunlight, oxygen or other gases, they will change quickly, which is uncontrollable for some cultural relics. For example, some ivory products were unearthed in southern China. These ivory products were white and smooth when unearthed, but they turned into dark powder in less than two hours.
Shape. "
Researcher Duan Qingbo, the captain of the archaeological team of the Qin Shihuang Mausoleum of Shaanxi Institute of Archaeology, said that it is the most suitable choice for people not to dig the Qin Shihuang Mausoleum at present, because the Qin Shihuang Mausoleum is too complicated and beyond anyone's imagination. Although some historical records have been confirmed, many things we know now are far from what we knew in the past.
According to the geological exploration of the Qin Shihuang Mausoleum in recent five years, it is found that there are symmetrical rammed earth steps and wooden structures in the wall, which are about 50 meters high and 350 meters in diameter. Before that, people thought enclosure was just a pile of rammed earth. The lowest height of the tomb is about 30m from the ground, the upper end is 160m long and 149m wide, and the bottom is 80m long and 50m wide.
According to historical records, it took Qin Shihuang about 38 years and about 720,000 people to build his mausoleum. In his underground palace, mercury was used to simulate the flow of rivers, lakes and seas in the territory he ruled, and the rotation of the sun, moon and stars was simulated above the underground palace. At the same time, the underground palace was full of organs to stop grave robbers.
Archaeologists have detected that the mercury concentration in the cemetery area is abnormally higher than that in the surrounding areas. After testing, it was found that mercury came from the sealed soil of Qin Shihuang's mausoleum. At the same time, it is found that Qin Shihuang used advanced drainage system to prevent groundwater from entering the underground palace. This drainage system is still used in the foundation construction of some modern buildings, such as the China Grand Theatre under construction in China.
1998 to 2003, the archaeological team of Qin Shihuang's Mausoleum conducted research on Qin Shihuang's Mausoleum and also excavated some tombs buried with him. The work was interrupted by lack of funds.
The inner city of Qin Shihuang Mausoleum covers an area of about 2. 13 square kilometers. If all kinds of burial pits have been found, it will reach 60 square kilometers.
After ending the rule of 15, at the age of 49, Qin Shihuang moved into the underground palace that he spent about 38 years building.
"Let Qin Shihuang and his underground palace continue to sleep underground, which is not only a respect for the deceased, but also the safest way to protect cultural relics." Mitchell Peset said.
Why didn't the mausoleum of Qin Shihuang be developed?
As for the "Hundred Rivers and Seas" made of mercury in the Qin Mausoleum recorded in historical records, the mercury content in the Qin Mausoleum is indeed extremely high. Flowing mercury flows into rivers and seas, which can not only make the underground palace magnificent, but also effectively prevent corrosion and theft. Once high-concentration mercury vapor is inhaled by human body, it will cause muscle paralysis, insanity and death. However, the current science and technology are not enough to stop the outflow of these mercury.

Why can't the mausoleum of Qin Shihuang be opened?
Please look at the interview record below, and you will know why you can't dig it.
Moderator: Although the exploration of Qin Shihuang's Mausoleum has solved several eternal mysteries, it still leaves people with many question marks. For example, what kind of treasures are there in the mausoleum of Qin Shihuang, and have they been stolen? Next, let's listen to the opinions of two experts. The first guest we connected today is Duan Qingbo, the captain of the archaeological team of Qin Shihuang Mausoleum. Hello. The second is Professor Wang Zijin, Vice President of China Qin and Han Historical Society. We very much welcome you to join our plan. First of all, I'd like to ask Captain Duan. Many people have such a question. You made a preliminary exploration of the Mausoleum of the First Qin Emperor. Does this mean that you may have to dig next?
Duan: This exploration is not directly related to the subsequent excavation, but the purpose is to have a clearer understanding of the overall layout of the cultural relics of Qin Shihuang's mausoleum, especially the general scope and structure of the underground palace of Qin Shihuang's mausoleum has nothing to do with the subsequent excavation. We have no plans to explore it now.
Moderator: Excuse me, Professor Wang, do you agree that the mausoleum of the First Qin Emperor will be excavated one day?
Wang: It will be excavated one day, but the conditions are still immature.
Orthographic image of cemetery
Moderator: What exactly do you mean by immature?
Wang: At present, the archaeological strength, funds, means of protection and research methods are not mature.
Duan: The excavation of the Mausoleum of the First Qin Emperor is not as difficult as we thought, but the protection of cultural relics after excavation, including how to protect such a large mausoleum and the types of unearthed cultural relics, really does not exist in China until now. During the excavation of Han tombs, we found a very obvious phenomenon, that is, the paintings on pottery pots rolled up with the excavation, which is very common. Therefore, it is very difficult to protect what kind of cultural relics, especially organic cultural relics, will appear in the underground palace of Qin Shihuang Mausoleum. We found that such a big pit could not be isolated from air at once, but could be isolated from oxygen at constant temperature and humidity. Even a few minutes of mistakes can cause fatal damage to cultural relics.
Moderator: Professor Wang, are there any historical problems or doubts that can only be solved when the mausoleum of the First Qin Emperor is excavated one day?
Wang: What amazing discoveries will be made in the underground palace? When I give lectures to students, I tell all about the life experience of Qin Shihuang. In the final analysis, it is his pedigree and his special relationship with Lv Buwei. Some students said they could do a DNA test. If Qin Shihuang's bones are still there, it is also possible to get them from King Zhuang Xiang's tomb.
Moderator: Your statement will definitely arouse the curiosity of the audience. What will be in this grave? I want to ask captain Duan. According to the current exploration situation, we can probably judge whether there is anything in this tomb.
Duan: We should have a reasonable guess about what kind of cultural relics will appear in the underground palace of Qin Shihuang's mausoleum during the same period, from the whole pre-Qin Dynasty to the early Han Dynasty. For example, national heavyweights, ding and reed are all bronze, including gold and silver cultural relics. It also includes some organic matter. What is most likely to be unearthed? Some bamboo slips and some wooden slips have been unearthed, which may contain a complete record of the history and present situation of Qin State. Why do you say that? At that time, many cultural classics were burned after burning books and burying Confucianism. If this kind of thing is unearthed again, its significance may not be great, and many historical and cultural problems may be solved.
Moderator: Professor Wang, many people say that you saw that Qin Shihuang's mausoleum only dug burial pits, such as the Terracotta Warriors and Horses Pit, but it was so shocking that you didn't know how many good things were in his tomb. Are all the historical materials recorded in this way?
Wang: Actually, what historians yearn for and hope most is the appearance of documents at that time. In addition, according to historical records, he collected a lot of treasures at that time, and there are some phenomena that we should be able to see when robbing the tomb. For example, there is a so-called crossbow in historical records, which is a machine specially used to shoot grave robbers and shoot them with bows and arrows. In addition, it is said that the rivers and seas composed of mercury provide some suspense for us to explore the mechanical history at that time. Because we know that this thing, like a perpetual motion machine, the setting of perpetual motion machine is of course a delusion. What was the form at that time? We saw the report of this investigation that there was an abnormal high temperature above the underground palace. ......
Why not develop the mausoleum of Qin Shihuang?
After nearly three years of investigation and research, Shaanxi archaeologists have come to the conclusion that the mausoleum of the First Qin Emperor is basically well preserved and has not been seriously damaged or stolen. So, when will this mysterious mausoleum open? Experts believe that according to the current conditions, many technical problems have not been solved, and the time for excavating the mausoleum of the First Qin Emperor is not yet ripe. The main difficulties are as follows:
1, Qin Shihuang's mausoleum is huge, with a mausoleum area of about 500 by 500 meters square. According to the usual archaeological procedure, it is necessary to uncover the top, remove the sealed soil layer by layer, and then dig it into the underground palace layer by layer. Needless to say, to protect the underground palace, it is necessary to build a permanent protection hall with a span of 500 meters. There is no precedent at home and abroad to build such a large-span hall, and the cost is extremely huge.
2. In addition, the groundwater level in Qinling area is quite high, and water will be seen at 16 meters above the ground. The underground palace is below 26 meters. When digging, if there is no extra-large drainage device, the whole underground palace will be flooded.
3. There is a lot of mercury in the mausoleum, forming a dense mercury sealing layer. How to pass through the sealing layer is also a problem.
4. How to save the unearthed cultural relics is also a big problem. Archaeologists encountered this situation when excavating the terracotta warriors and horses in Qin Dynasty. At that time, the soil was open, and the terracotta warriors and horses were all brightly colored painted pottery, but soon after they were unearthed, all the colors faded and became all taupe. A large number of silk fabrics were unearthed in Dingling, Beijing, including a dragon robe. At that time, the most advanced technology in the world was adopted for protection, and the result still failed. With a slight movement, the dragon robe may become a pile of fragments or powder. At present, these technical problems have not been solved, so the mausoleum of the First Qin Emperor cannot be excavated for the time being.
Why not dig the Mausoleum of Qin Shihuang?
The discovery and excavation of Qin Terracotta Warriors and Horses Pit, Qin Tongche Horse Pit and Qin Shijia Armor Pit shocked the whole world. When people marvel at this great historical miracle, they will naturally look to the underground palace of the mausoleum of the First Qin Emperor, the mother of this great miracle. This will be a more mysterious and fascinating great miracle.
The underground palace under the seal of Qin Shihuang's mausoleum is about 30 meters deep from the present surface. There is an approximately square underground wall around the underground palace. As for the situation in the underground palace, Sima Qian recorded it in Records of the First Qin Emperor: "At the beginning of the emperor's accession to the throne, he penetrated Mount Li and melted into the world. More than 700,000 people were sent to the world, and after three springs, they went down to Tongquetai and pulled out the shackles. The scenery of the palace is full of strange things. Let the craftsman make a crossbow, and people who wear it at close range need to shoot it. Take mercury as a hundred rivers and seas, and instill it by machine. There is astronomy above and geography below. Taking mermaid cream as a candle will last for a long time. " In other words, the underground palace of Qin Shihuang's mausoleum is like Xianyang Palace in Qin Dynasty, with hundreds of officials in it. The roof of the underground palace is built with carved stones and pearls to mark the sun, moon and stars, and the ground also marks all rivers with mercury. Moreover, in this underground palace where countless exotic animals and articles are buried, there are candles made of mermaid cream (said to be a quadruped fish that looks like a human in the East China Sea) burning endlessly, making the underground palace look like a day all year round. In order to prevent grave robbers from entering, craftsmen made a magical secret crossbow in the underground palace. When the grave robbers approached the tomb door, they were shot outside the tomb.
Because the underground palace was not excavated, Sima Qian's description could not be confirmed. However, in February of 198 1 year and May of 1982, geologists conducted two tests on the underground palace with modern instruments, which proved that there was a strong abnormal mercury reaction in the underground palace, with an area of 12000 square meters and a slightly geometric distribution. This confirms Sima Qian's record of "taking mercury as a hundred rivers and seas". After the Qin Terracotta Warriors and Horses were unearthed, after more than ten years of efforts by multidisciplinary scientists, part of the mystery of the underground palace of Qin Shihuang's mausoleum was gradually solved.
According to archaeological investigation data, the upper point of the underground palace of Qin Shihuang's mausoleum is approximately square. The underground palace wall was found at a depth of 2.7-4 meters from the present surface. The palace wall is 392 meters wide from east to west and 460 meters long from north to south, with a total area of about 6,543,800 square meters. Such a tomb is unique in Chinese and foreign history. The palace wall is about 4 meters high and 4 meters wide, and is made of unfired bricks. There are doors on all sides of the palace wall, five in the east and three in the other 1. The underground palace under the seal is about 30 meters deep from the present surface. The place where the coffin is placed is called Xuan Palace, which is the core of the underground palace and undoubtedly located in the center of the palace wall.
In a word, this magical underground palace, like the palace before Qin Shihuang's death, continues to place his "eternal" wish in the underground kingdom.
Was the mausoleum of Qin Shihuang stolen?
Qin Shihuang's works are famous for their huge scale and unprecedented burial. Everyone who cares about the mausoleum of Qin Shihuang is very concerned about whether it was stolen. Judging from the ancient history of China, the last few years of each dynasty were the most chaotic period, with the hegemony of the pack, bandits running rampant and the whole society in a state of no * * *. This is a good time for grave robbers to dig graves, and almost all tombs of past dynasties were stolen at this time.
Xiang Yu's Destruction of Qin Shihuang's Mausoleum
According to historical records, after Xiang Yu led his army into Guanzhong, he first killed Prince Ying of Qin and the nobles of Qin royal family who had surrendered to Liu Bang, then plundered Xianyang City and finally set it on fire. Then, Xiang Yu led his troops to the Mausoleum of the First Qin Emperor, and ordered the soldiers to dig the Mausoleum of the First Qin Emperor and carry away everything that could be seen up and down the Mausoleum. At that time, there were 300,000 people carrying things, which have not been shipped for more than 30 days, showing the richness of treasures in the mausoleum. Finally, Xiang Yu set fire to what he couldn't walk, and it burned for many days. This may be the earliest and most destructive disaster in Qin Shihuang's mausoleum.
After Xiang Yu's eastward expedition, thieves from Kanto poured into the mausoleum of the First Qin Emperor. It is said that the bronze coffins in the mausoleum were destroyed to get copper. Later, it was said that a shepherd boy was herding sheep here. The sheep went into an underground cave dug by the rebels and could not be found. The shepherd boy took the torch and went into the grave to look for the sheep. The result was a fire, which lasted for more than 90 days. It is said that with the collapse of some burial pits and graves, the ground of dozens of miles in Fiona Fang Mausoleum Area has also sunk several meters. In this way, the ground buildings of Qin Shihuang's mausoleum disappeared, and the underground tombs were also damaged to some extent. These records are supported by today's archaeological discoveries. Almost all burial pits and graves found in Qin Shihuang's mausoleum were damaged by theft and fire.
After four years of Chu-Han War, Liu Bang defeated Xiang Yu and established the Western Han Dynasty. In order to win the hearts of the people, BC 195 ......
Why not open the mausoleum of Qin Shihuang now?
Even if we have the technology to ensure that the ancient tomb will remain as original as possible after it is opened, and even be left unscathed, what about after it is opened? Can the relevant cemetery protection facilities keep up? Now the state funds are getting more and more tight, and there are more and more corrupt officials ... Do we have the manpower and material resources to do a good job in the aftermath and research of opening ancient tombs? Don't be selfish and say, "How do you know how many treasures are inside if you don't open them?" Do you know how big the Qin Mausoleum is? Do you know how hard it takes to protect an ordinary cultural relic that is afraid of oxidation? ! There is not much treasure in the ancient tomb. That's easy to say. If the number is amazing, have you thought about where to put those things? Can you guarantee perfection? If there is any loss, I'll see how you tell your children and grandchildren! ! What history expert? This is! ! ! Just want to satisfy your curiosity! ! I think this decision made by our country is wise and accords with the current situation in China. If the funds for cultural relics protection are astronomical, I think it is better to use them all for disaster relief and poverty alleviation! ! So many people have not solved the problem of food and clothing! So many children have no books to read! ! How can the country's money be so abused!
Why doesn't Qin Huangling open?
Because there are 200 tons of mercury in it, how to open this mercury and how to deal with it? There is also the protection of cultural relics, because infantry is open. In the past, when they were opened, footmen were painted and shaped into real people. Now it's all oxidized into clay figurines. Therefore, it will not be opened without considering how to prevent oxidation!
Why hasn't the mausoleum of Qin Shihuang been opened yet?
First, the layout embodies the characteristics of single burial. In the cemetery of Wang Wei discovered in the past, there are three tombs juxtaposed, and there are also five tombs arranged in the cemetery of Zhongshan King. There is only one tall mausoleum in Qin Shihuang's mausoleum.
Mausoleum of the First Qin Emperor
It fully shows the characteristics of a burial. The layout of other monarchs' cemeteries presents the characteristics of multi-center of monarch, queen and wife. This difference is the reflection of Qin Zunjun's traditional thought of following the minister in the layout of the mausoleum.
Second, the location of the mausoleum is also different from other monarch cemeteries. Most of the cemeteries of other monarchs are located in the middle of the Hui cemetery, while the mausoleum of the First Qin Emperor is located in the southern half of the inner city. Some gentlemen think that this is arranged according to the etiquette of "the west is the best". Judging from the overall layout of the cemetery, the tomb of the first emperor is not in the western half. The reason why the enclosure of the home was built in the southern half of the cemetery was decided by the design idea of "planting trees and grass like mountains".
Third, the tomb has a strict anti-theft system. It is often said that there is an anti-theft device in the underground palace of Qin Shihuang's mausoleum. It is often unclear which anti-theft mechanisms are available. According to legend, a thick layer of sand was filled around the underground palace of Qin Shihuang Mausoleum, forming a sand sea. This sand sea is the first line of defense of the underground palace of the Qin Mausoleum, which makes it impossible for grave robbers to enter the tomb by digging holes.
If the sand sea is just a legend, then the dark crossbow is clearly recorded. Sima Qian affirmed in Historical Records that there was a hidden crossbow in Qin Shihuang's mausoleum. When thieves enter the mausoleum and touch the organ, they will be shot to death with a strong crossbow. Mechanical devices matched with concealed crossbows and traps. Grave robbers will fall into a trap and die even if they are not shot. In addition, there is a lot of mercury in the underground palace of the Qin Mausoleum, and the gas evaporated by mercury contains poison, which will also kill grave robbers. It can be seen that the anti-theft system of Qin Shihuang's mausoleum is quite strict.
