The mystery of the layout of the Forbidden City, why is the Forbidden City uneven and a little inclined?
When the Forbidden City was built, it was tilted a little to prevent water from accumulating inside the Forbidden City during the rainstorm. Some tilts can ensure the drainage of water. When the Forbidden City was built, its surroundings were square and symmetrical. In order to prevent someone from entering the palace with bad intentions to assassinate the king, the Forbidden City was designed to be difficult to get in and out when it was built. However, there is also a drawback. The Forbidden City, which is too closed, may also lead to the water flow not being discharged in time, so the designer considered this problem during the design, so he chose to build the Forbidden City with a little inclination.
From the appearance, there seems to be nothing wrong with the Forbidden City, but after careful observation, we can still find that the Forbidden City is somewhat tilted. The Forbidden City is like a besieged city, and the walls include all the palaces inside. However, once it rains heavily, it is very likely that the drainage system inside the Forbidden City will collapse. Although Beijing where the Forbidden City is located is in the north, it rains less, but once it rains heavily, it is too late to drain the inside of the Forbidden City. In the Ming dynasty, there was a rainstorm in Beijing, which almost flooded all the city gates, so we had to take precautions.
In fact, when the Forbidden City was built, the terrain was not specially leveled, but it was built along the terrain. There are mountains in the north of Beijing and Bohai Sea in the east, so the terrain determines that the Forbidden City will not be flat. Furthermore, in order to prevent water from accumulating in the Forbidden City, many ditches were dug inside the Forbidden City. The sloping terrain of the Forbidden City allows the accumulated water in the Forbidden City to be directly discharged according to the terrain, which is the biggest advantage of the sloping terrain of the Forbidden City, so the Forbidden City has never been affected by heavy rain, thus being submerged.
The construction of the Forbidden City is indeed a great building in the history of China. I don't know how much manpower and material resources were spent in the construction, and finally the magnificent Forbidden City we see today was formed. The construction skills of the Forbidden City and the culture contained in it are worth exploring, and they are also an important carrier for us to study the ancient culture of China.
