Because jade is the exclusive item of ancient rich families, ordinary grave robbers can't sell jade, but they are also easily suspected by others and may be arrested by the government.

Tomb raiding has existed since ancient times. In the eyes of grave robbers, ordinary people's seemingly gloomy graves are a shortcut to get rich. From farmers to lean men of an era, they are all jealous of the gold and silver in this tomb, and one by one they abandon morality and join the army of grave robbers. One of the most famous, and the first person to rob a tomb on a large scale, was Cao Cao, a valiant soldier of the Three Kingdoms. It is reported that at that time, in order to solve the problem of insufficient military pay, Cao Cao specially selected those who were fearless and not afraid of death to set up a tomb raiding army, and named it Mojin captain according to the nature of their work. He dug the tombs of ancient princes and nobles everywhere and brought back a car full of gold and silver to buy food and pay for the army.

In the past, folk grave robbers were not as blatant and unscrupulous as official thieves. They even have their own rules and regulations. After entering the tomb, they only took some funerary objects to solve their living problems. They never destroy the grave owner's body, nor take all the treasures, but always leave some behind. This is the so-called "you can't do everything too well", which used to be called "stealing". It is said that in ancient times, when robbing a tomb, the general grave robbers only took funerary objects that were sold well, such as gold, silver and copper coins, and rarely took jade and jewelry, especially jade that could not be moved. Why? Is jade worthless?

In fact, jade was a very valuable thing in ancient times. There has always been a saying of Baoyu in the past. Rich people always take a few pieces of jade with them. People like to compare the elegance and cleanliness of jade to noble character, which makes jade a symbol of a rich family. Ordinary people don't have the economic ability to buy jade. If grave robbers steal jade, they won't sell it, but they are easily arrested by the government. Therefore, it is useless for grave robbers to take jade, but it will harm them.
