Speaking of the Forbidden City, we should all be more familiar with it, the Forbidden City, as the most magnificent ancient building left over from Chinese history, is also a major treasure left by the ancestors, the houses of the Forbidden City are very magnificent, even after so many years of feng shui and sun, but the glazed tiles of the Forbidden City are still bright!
The Forbidden City was decided by emperor Zhu Di of the Ming Dynasty to move the capital to Beijing and began to build it, until the eighteenth year of Ming Yongle's completion. The building covers an area of 72 square meters, of which the building covers an area of 150,000 square meters, and is the imperial palace of 24 emperors of the Ming and Qing dynasties. There are more than 70 large and small palaces and more than 9,000 houses in this Forbidden City, which can be called one of the largest and most well-preserved wooden structures in the world. How, isn't it particularly vast? Then of course, this Forbidden City is a national treasure of the mainland, and since it is a national treasure country, it will certainly be specially protected, but it is inevitable that natural disasters will come.
Thinking that when the Forbidden City actually had an earthquake of more than ten levels, everyone thought that these ancient buildings would definitely be destroyed some times, but they did not expect that they were not destroyed, so people's eyes suddenly observed the underground of the Forbidden City from the surface of the Forbidden City, what is it that can make this Forbidden City resolutely resist the earthquake of more than ten levels?
Experts also do not dare to dig open the ground of the Forbidden City to take a look, a normal Forbidden City repair work people found that several floor tiles appear damaged according to common sense they need to clean up the bad and then clean up the dust residue for repair, the result is that under the floor tiles is another floor tile, after opening up there is another floor tile, experts have a row down fifteen floor tiles, and the format of the 15 floors is not the same, these paved such cumbersome floor tiles are obviously considered if the enemy digs tunnels to prevent assassination.
These floor tiles of the Forbidden City are very expensive, comparable to an inch of gold bricks and an inch of gold, so what materials and methods are used for these floor tiles? The ancient books record that the production process of such a floor tile takes 720 days, and the process conditions are extremely harsh, and there are seven processes for only soil selection, and these processes take 7 months to complete. It is more complicated to burn in the kiln, and if there are 6 pieces of the whole kiln that are not qualified, they will all be abandoned.
Then Zhu Di took such great pains to prevent assassinations, and the fate of those craftsmen who built the palace was stifled, and everyone knew that Zhu Di was an extremely murderous person. At the beginning of the construction of the Forbidden City, he ordered the craftsmen to eat a special poison to destroy people's throats, so that they could not speak. After completion, in order to keep the secret, Zhu Di ordered the killing of all the craftsmen who built it.
After all, they were building a royal palace, and they should have understood at the beginning that this emperor would not leave anything unfavorable to him in this world, let alone such a big thing as building a palace.
