The main body is Daming Hall, and the main body in the north is Yanchun Pavilion. Daming Hall, also known as Changchao Hall, was built in the 10th year from Yuan Dynasty to Zhengzheng (1273). It is the largest building in the capital of the Yuan Dynasty, and some important ceremonies of the Yuan Dynasty, such as the emperor's accession to the throne, New Year's Day and birthday celebrations, were held here. The pavilion behind daming temple is Yanchunge. It is higher than the Daming Hall, where rulers of the Yuan Dynasty often hold Buddhist and Taoist ceremonies and sometimes hold banquets.
In the fifteenth year of Yongle (14 17), Judy, the founding emperor of the Ming Dynasty, built a palace. Although the northern city was reduced to South Wuli in the early Ming Dynasty and the location of the new palace was moved south, it was still within the planning and design scope of the Ming Palace. ? According to the traditional geomantic theory, the Forbidden City must be "surrounded by mountains and waters". ? As a result, the demolition of palaces in the Yuan and Ming Dynasties and the excavation of flooded soil in the moat of the Forbidden City piled up into a mound mountain with a height of more than 40 meters, named "Long live the Mountain", and its main peak was the former site of Yanchun Pavilion.
In this way, the "Long Live Mountain" not only echoes the Jinshui River in the south, but also intentionally suppresses the "Feng Shui" of the previous dynasty. For this reason, "Long live the Mountain" is also called "True Mountain". In the Ming Dynasty, pavilions and temples were built here, pine and cypress were planted along the slope, and rare birds such as cranes and deer were raised, which meant longevity.
Therefore, long live the green cypress, countless flowers and quiet scenery. During the Wanli period of the Ming Dynasty, Zhu Yijun came to the top of the mountain every year on the Double Ninth Festival of the ninth lunar month to pray for disaster relief and longevity.
The peak selection in "Long Live Mountain" is not only on the central axis of the whole city, but also in the middle of the north and south ends of the inner city, becoming the center of the whole city of Beijing after reconstruction. ? From Zhengyangmen to the north along the Imperial Road, we passed Daming Gate, Chengtianmen, Duanmen, Wumen and Fengtianmen in turn, and then arrived at Fengtiandian, where we passed through six enclosed spaces of different sizes and shapes, with a total length of more than 1700 meters, and left the north gate of Miyagi-Xuanwu Gate (the Shenwumen in the Qing Dynasty) and the wonder of "Long Live the Mountain".
Therefore, although this artificially shaped commanding height has no obvious practical value in the whole palace building, it has a very prominent symbolic significance, which shows the supreme dignity of feudal emperors.
