The Forbidden City, as the palace of the Qing Dynasty and the Ming Dynasty, naturally has a lot of historical charm. So far, it has been more than 600 years. However, when many people visit the Forbidden City, they find that although the Forbidden City has a long history, it has not been damaged too much, but only a few small courts have been affected, and it is still the kind that does not hurt the grand elegance.
Now, as an open scenic spot, the Forbidden City can be entered as long as you buy tickets. So we can see that this building is really great. It must have been built by the builders in ancient times. After more than 600 years, it can still maintain the perfect appearance of the palace. Some people go to the Forbidden City and think that even our houses now have a lot of bird droppings. Why didn't the ancient Forbidden City have bird droppings so far?
Even if someone cleans the roof every day, there's no way to clean it. It's said that there hasn't been too much bird droppings on the roof of the Forbidden City for more than 600 years. According to experts, the reason for this is that it has a lot to do with the design of the building. If you look closely at the Forbidden City, you can see that the design of the Forbidden City is very special, and few birds will stay on the roof and eaves of the Forbidden City.
Its eaves slope is particularly large, especially the tiles on the roof. Even if the bird claws can no longer grasp the column, they can't stay in such a slope and smooth place for too long. Birds would not like such a place if they could slide down without moving. Moreover, the pillars on the eaves are also very smooth, and the birds have no way to stand there at all. So if the birds seldom go there, how can they leave bird droppings?
Even if the bird excreted bird droppings from the sky and dropped them on the roof, it would slide to the ground in an instant because the roof was too inclined and bright. In this way, when the bird droppings are dry, they will fall on the ground, and other people will clean them up. Naturally, they won't worry about the bird droppings on the Forbidden City. In fact, this kind of design is not accidental, but it was thought of in advance by the designers and construction workers of that era when the Forbidden City was under construction.
