In China's history and culture, ancient buildings are very precious cultures, and there are still many ancient buildings, which are deeply protected by the state. Everyone knows the Forbidden City, which is a very magnificent palace, it is the palace of the two dynasties of the Ming Dynasty and the Qing Dynasty, and it has existed for more than 600 years. After hundreds of years, many ancient buildings have disappeared, but the Forbidden City has not fallen for 600 years.
After hundreds of years of ups and downs, the Forbidden City will still be damaged to some extent, and after the founding of New China, the state has repaired the Forbidden City. In the process of restoration, after the floor tiles in the Forbidden City were pried open, a secret was discovered, and experts said: Zhu Di's heart is really fierce! Floor tiles can be seen everywhere in the Forbidden City, but the floor tiles in the Forbidden City are very precious and not affordable for ordinary people.
However, the Forbidden City has not fallen for more than 600 years, and the secret of this is hidden under the floor tiles, what is it? The bricks of the Forbidden City are well-made, while the bricks in the Forbidden City have a very small error between each piece. After the production is successful, it still needs to be strictly screened and cannot be used directly. It can be seen that the gold bricks laid by the Forbidden City have consumed a lot of manpower and material resources, and it can be seen that the construction of the Forbidden City is rigorous.
However, this project is already very labor-intensive, and it is not easy to lay one floor, but the floor tiles of the Forbidden City are paved with fifteen floors. This is the hard work of countless laborers, but many people do not know that in order not to let the secrets of the Forbidden City floor tiles leak out, these workers who make gold bricks have all become dumb. After watching the fight, the experts had to sigh: Zhu Di's heart is really fierce! These laborers are so pitiful.
