There are many traditional ways to prevent grave robbery. The most common thing is to hide the address, so that people can't find it. For example, the tomb of Nanyue King in Guangzhou. There are also suspected tombs. For example, when Gao Cheng buried his father Gao Huan in the Northern Qi Dynasty, he set up a virtual tomb. Cao Cao, it is said that 72 suspected tombs have been erected. Although there are not so many legends, the establishment of virtual tombs is also a major form of ancient aristocratic robbery prevention. In addition to making a fuss about the address, the ancients also used many methods to prevent grave robbery:

1. "Fu Huo". At the end of Qing Dynasty, the Tufuzi near Changsha, Hunan called this fire-breathing tomb "fire pit tomb" or "fire hole". 1972, during the excavation of Mawangdui 1 Han Tomb in Changsha, workers drilled several holes with steel drills when excavating the white plaster mud layer, and a cold air gushed out from the holes, which would burn in case of fire! Not only the funerary objects of the whole tomb are intact, but even the skin of the female tomb owner is still elastic!

2. "Poisoning" When it comes to poisoning, I'm afraid Ying Zheng, the first Qin Emperor, was the most successful. He used mercury as a river and sea in his tomb, and mercury volatilization has not failed so far! According to archaeological investigation, there is a 12000 square meter "mercury anomaly" in the mausoleum of the First Qin Emperor.

3. "Machine crossbow" The machine crossbow of Qin Shihuang's mausoleum is also world-class. Poor craftsmen who design mechanical crossbows don't know how many brain cells died when they made these super-cutting mechanical design schemes. 1985 Twenty-five pieces of copper tribulus were found in the Han Tomb in Qinglong Township, Chengdu, which should be a unique hidden weapons against grave robbers.

4. "Water storage" As the saying goes: dry for a thousand years, wet for ten thousand years. Storing water in the tomb can not only drown the grave robbers, but also preserve the owner's body for a long time.

5. "Sand accumulation" According to archaeological data, sand accumulation may be the most widely used means to prevent grave robbery. Tomb 1, 2/and 3 in Guwei Village, Huixian County, Henan Province, excavated at 1950, is considered as the resting place of the royal family of Wei State during the Warring States Period. The tomb was built of huge stones and filled with fine sand.
