What is the "yellow intestine inscription" in the tomb of the ancient emperor? Why are thieves afraid to meet it?
After all, everyone has to face death, which is unavoidable. However, people's attitudes toward death are different. We modern people think that there is nothing after death, but the ancient people felt that after death, another life will begin.

The ancients all thought that after a person dies, the soul will not be destroyed, it will go to another world, and then it will still exist. Those emperors will live a very luxurious life before they die, so when they face death, they hope that after going to the "kingdom of heaven", they can still live the previous life, and then there is a custom of thick burial.
In fact, a thick burial is to put a lot of precious funerary objects in the mausoleum, first of all, to highlight how noble their identity is, and secondly, for them to go to another world for consumption. This ethos has lasted for thousands of years, and their tombs have become treasure troves of artifacts.
This custom makes tomb robbers often go to the tomb, so many precious treasures have been stolen.
In order to prevent the treasures in those tombs from being stolen, the ancients also came up with a lot of methods. In the Qing and Han Dynasties, the method of "yellow intestine inscription" was popular, and many tomb robbers had no way to do anything when they encountered this.
So what is it?
It is actually like a wooden box around the outside of the coffin, and the location of the coffin is the core. The "yellow intestine" is actually a material, this cypress core is peeled, although the color is yellow, it is relatively light. The "inscription" is a direction of arrangement, where the coffin is the center and the wood is arranged in a centripetal manner.
So how big is it?
It should be known that the wood of cypress is very solid, and it still has grease in it, and its water resistance and corrosion resistance are relatively strong, so even if it is buried in the ground for thousands of years, it will be intact.
After this wood is made, its cross-section is square, and each side is about twenty-one centimeters long, and each piece of wood is about 5.6 meters to 7.3 meters, weighing about 300 kilograms. The wood is so strong when it is added up and fixed that it is extremely difficult to move.
In fact, its most core technology is the direction of its arrangement, so the tomb robbers actually have to face the ends of these cypresses, and they can only approach the coffin after removing these woods.
But how do you get rid of these cypresses? It's already so solid, plus it's more than one layer.
And some of the tops are even combined with the dome, if you use violent methods, then the burial chamber is likely to collapse, so the tomb robbers are very afraid of this.
Later, some grave robbers used the means of blasting, but it was useless, and they were eventually arrested.
