The Yangxin Hall is about 94.8 meters long from north to south, about 81.3 meters wide from east to west, and covers an area of about 7,707 square meters.
Foreword: Although the Forbidden City has been studied for many years, there are still many secrets that have not been discovered by experts, which also shows that the Forbidden City has a lot of wisdom of the ancients when it was built, and the cultural relics protection system also makes it difficult to find many secrets of the Forbidden City. For example, there has been a problem of perennial humidity in the Forbidden City Yangxin Hall, which has also plagued experts for a long time.
It is in a humid and cold state for a long time
The Yangxin Hall can be said to be the central location of the Forbidden City, and it was also an area where many emperors rested and discussed government. In terms of the construction wisdom of the ancients, the Yangxin Hall should not be so damp and cold, because it is the place where the emperor lives and works, and if it is too humid, it is not suitable for the emperor's office.
However, after Chinese experts began to study the Forbidden City, they have been plagued by such questions. How could such a very important central location, and the place most often used by the emperor, be such a humid environment. From the perspective of the supremacy of imperial power in feudal society, such a thing was not allowed to happen, and it was impossible to choose the Yangxin Hall in such a cold and humid environment.
With such doubts, experts have also carried out some research on the Yangxin Hall, but there has never been a perfect inference, and this matter has become a mystery in the Forbidden City. Until one time there was a water leakage problem in the underground of the Yangxin Hall, in order to ensure its integrity, but also in order to make the cultural relics better preserved, a series of waterproof measures began.
Discover the secrets of the underground of the Yangxin Temple
Because the water leakage is more serious, experts have also carried out waterproof measures on the underground of the Yangxin Hall. But after the floor tiles were removed, the experts were shocked by the sight in front of them, because there were many "water pipes" under the floor tiles. This is not a water pipe in the actual sense, but a tubular structure composed of rotors and tiles.
It is precisely because of these pipes that the temple that should be dry will become damp. The experts analyzed these pipes, excavated the underground of all the Yangxin Hall, and found that such pipes were laid throughout the yangxin hall, and there was still some residual moisture in these pipes.
The presence of these waters was also the main factor in the perennial humidity of the Yangxin Hall, because after the end of the imperial rule, these pipes were left unpowed, and there was always some residual moisture in them. These waters continue to evaporate over the years, leaving the Yangxin Hall in a relatively humid state.
The wisdom of the ancients is admirable
After discovering these pipes, the experts also knew the main reason for the perennial dampness of the Yangxin Temple. But I still admire the wisdom of the ancients, because this is similar to the current "floor heating". It can make the Yangxin Hall warm in winter and cool in summer, and in the winter, it can be filled with hot water into the pipe, which can make the Yangxin Hall warmer; in the summer, it will make the whole palace very cool.
Such a engineering volume is very huge, and it also reflects the wisdom of the ancient people's life. This also shows that the Yangxin Hall is indeed one of the most important palace groups in the Forbidden City, because only the supreme imperial power can enjoy such treatment. Because of the maintenance of the Yangxin Hall, the experts found out the reason why the palace was wet all year round.
To sum up: there are still many secrets in the Forbidden City that have not been discovered, and behind these puzzles may be the same reason as the dampness of the Yangxin Hall, in addition to the wisdom of the ancient craftsmen, it is also necessary to start from the essence of imperial rule, because most of the wisdom inventions in that period are inseparable from imperial power.
