The existing central axis in Beijing is the one used in the Yuan Dynasty. In the Ming dynasty, it moved south, but the direction of the central axis remained unchanged. Ming City was used in the Qing Dynasty, and its central axis has not changed, with a history of more than 700 years.
In the geomantic work before the Yuan Dynasty, according to the wishes of the emperor Kublai Khan at that time, in order to reflect the unity of the two capitals, the connecting line of the two capitals was adopted as the baseline of the central axis of the metropolis.
Therefore, the phenomenon that the central axis and meridian of the Forbidden City do not coincide and deviate is produced.
Extended data
The central axis of Beijing starts from Yongdingmen in the south and ends at the Bell and Drum Tower in the north, with a length of about 7.8 kilometers. It is called "the backbone of Beijing". From south to north, there are nine gates, namely Yongdingmen, Zhengyangmen, Tiananmen, Duanmen, Wumen, Taihe Gate, Gan Qing Gate, Shenwumen and Di 'anmen, dotted with dozens of royal gardens and residential quadrangles along the way.
Mr. Liang Sicheng, Ceng Dian, commented that Beijing's central axis is the longest and largest north-south axis in the world. "Beijing's unique grand order is produced by the establishment of this central axis."
The existing central axis of Beijing was determined when the city was built in the Yuan Dynasty, and it has not changed since the Ming and Qing Dynasties. When planning and designing the capital of Yuan Dynasty, Liu, an important official of Yuan Dynasty, first determined the position of the central axis, which is the connecting line between Yongdingmen, Zhengyangmen, Duanmen, Wumen, Hall of Supreme Harmony, Shenwumen, Di 'anmen Drum Tower and the main entrance of Bell Tower.
Public trust. Com- the mystery of Beijing's central axis deviation: it is not due south and due north pointing to Yuanshangdu.
