When it comes to world cultural heritage, the first thing that comes to mind is the Palace Museum in Beijing. It can be said that a simple Forbidden City, enough for all experts to study for decades, the profound truth it contains, can not help but make people sigh, even if the small floor tiles are actually in each of our families, but it is an ordinary thing, but if it is placed in the Forbidden City, it is different, in fact, the Forbidden City floor tiles have also been walked by countless people for a hundred years, and nothing has ever been found wrong, until one year the Forbidden City ground cracked, revealing the traces inside, people understood the secrets.
The floor tiles of the Forbidden City are made of a special material, which is stronger than ordinary bricks, which is the so-called "sound of knocking, no hole in the break". The production time of a brick in the Forbidden City is very long, and its cost is equivalent to one or two gold bricks, so it is called "golden brick" by the people. Now the value of the floor tiles of the Forbidden City as cultural relics is very high, and it is said that the auction price of a pair of imperial kiln gold bricks during the Yongle period is as high as more than 800,000, which is shocking.
In fact, under the floor tiles of the Forbidden City, there is still a secret that no one knows, and this secret has to start from a major earthquake. After the Tangshan earthquake, although the Forbidden City hundreds of miles away was also affected, the buildings were not damaged, but the floor tiles in places such as the Taihedian Square of the Forbidden City were somewhat broken. So the experts sent people to repair it, but when the workers dug out the top floor tiles, they found that there was an identical floor tile underground.
Then, driven by curiosity, the craftsmen successively removed the floor tiles below, resulting in layer after layer, and finally the whole person went deep into the ground, which was considered to be completely moved, about fifteen floors in total. And these fifteen floor tiles, not arranged according to a certain law, but dense, disorganized, although the experts racked their brains, but did not think of any architectural principles, in fact, we ordinary people in the construction of houses, there will also be the behavior of laying the foundation, but generally will not use bricks, but with some sand, dirt, although the palace is different from the ordinary people's homes, but in any case do not need so many bricks.
It turned out that the reason why so many layers of floor tiles were buried in the ground, one was for the safety of the emperor, everyone knew that the emperor was a high-risk profession, and he would be targeted at every turn, assassinations and the like were commonplace, in order to prevent unscrupulous elements from digging tunnels to assassinate the emperor, so so so they stacked so many layers that they could not dig. Second, in order to prevent the land from collapsing, so many layers of floor tiles are superimposed. The wisdom of the ancients cannot be underestimated.
