It is believed that the roof of the Forbidden City has always been clean, dust-free, and bird-free since its construction. The reason lies in the calculation of the ancients when building.

The Forbidden City (also known as the Imperial Palace) in Beijing was built in the Ming Dynasty and has been around for 600 years, this is one of the largest wooden-built ancient structures in the world. still exist today. Accordingly, the Forbidden City is 720,000 m2 wide with 800 large and small palaces.

The name Forbidden City originally comes from the word "Tu" in the Zodiac Palace or Thien Tu with the meaning of the son of heaven. Because the place of residence of the Heavenly Emperor is the Tu Vi Palace, the place of the Son of Heaven is also added with the word "Tzu". And "Forbidden City" means that the city is strictly forbidden for civilians to enter.

The Forbidden City is known as the place to discuss the affairs of kings and their courtiers. This is also the residence of the emperor and his harem, in addition to eunuchs and palace maids who are their servants.

Today, the image of the Forbidden City has become one of the famous wonders of the world. Because the Forbidden City has thousands of years of history, this place also contains many mysteries that posterity always wants to discover.

The Forbidden City was built based on a mythical story called "Fairy Horoscope". The story goes that there is a place called Zi Wei palace (a purple palace) where the Jade Emperor and the gods reside. In this place, the Emperor is called the son of heaven and the new palace is majestic enough to be worthy of him.

Therefore, Chinese emperors considered the Forbidden City to be a symbol of power. This work was built in 15 years (1406 - 1420) with the contribution of 1 million people. The Forbidden City is considered the pride of the Chinese people by its magnificence and grandeur.

The Forbidden City is a testament to the luxury of the place where the Emperors of China once lived. This work also clearly shows the traditional Chinese imperial architecture and contains the quintessence and talents of the ancients when building the Palace.

Many history buffs of these two dynasties were attracted by the magnificent palace architecture. As soon as entering the Forbidden City, visitors will be overwhelmed by the magnificent hall, shiny glazed tiles that make everyone admire and be curious about the wisdom of the ancients.

The preservation of historical structures is actually not easy, in fact there are many precious structures that are not only eroded by wind and rain, but also destroyed by bird droppings.

However, the Forbidden City did not encounter bird droppings, why is that?

It can be said that the Forbidden City is an old architectural work with a history of more than 600 years that is still well preserved. But what if birds flew by to disturb the emperor or defecate on the roofs and walls of the palace. After thinking, the researchers tried to explore the roof of the palace to find the answer.

Those who are interested in the Forbidden City know that this work uses yellow glazed tiles. Yellow glazed tiles and red walls are the colors symbolizing the power of the royal family. The design of the roof is also intended to highlight the power of the royal family. These are also the two colors that birds are quite afraid of.

In addition to the smooth surface, the roof of the Forbidden City is still referenced at a certain angle, and the craftsmen of that year also adopted a design method called the "top wall" that is, the design of the roof top makes it impossible for the birds to rest on it, which also means that the design is to prevent the birds from nesting there.

Not only thanks to the design method mentioned above, manual builders have built in the style of ridges on the main wall or ridges on the roof so that the distance between each brick is designed to be larger than the distance between the legs. birds, so that when the birds want to stay on it, it is also very difficult to stay, just stop for a moment and then quickly fly away.

In addition, the ancients used a paint with a special smell, which indirectly made birds not want to come near.

Having existed for more than 600 years, the Forbidden City still occupies the position of the largest palace in the world. The construction architecture at that time reached a very skillful level, so the hypothesis that the design of the glazed tile roof was always clean and beautiful, the birds did not dare to perch was completely valid.
