During the Ming and Qing Dynasties, except for the corner to the north of Xizhimen, Beijing was basically symmetrical according to the central axis of the Yuan Dynasty (it can be clearly seen from the satellite map that the Forbidden City in Beijing was tilted to the west), but the central axis to the north was revised.

The buildings along the central axis of Beijing in Ming and Qing Dynasties were Yongdingmen Arched Tower (demolished in 1957), Yongdingmen Tower (demolished in 1957 and rebuilt in 2005), Tianqiao Bridge (demolished in 1934), Zhengyangqiao Square (five archways) and Zhengyangmen Arched Tower (demolished in 2005). 1954), Tiananmen Square, Duanmen, Wumen, Taihe Gate, Taihe Hall, Zhonghe Hall, Baohe Hall, Gan Qing Gate, Gan Qing Palace, Jiaotai Hall, Kunning Palace, Kunning Gate, Royal Garden, Qin 'an Hall, Shunzhen Gate, Shenwumen, Beishangmen (1955

Most buildings in the Forbidden City are east-west symmetrical. The main buildings such as the Hall of Supreme Harmony are located on the central axis.

People found stone rats in the mud of Houmenqiao and stone horses in the river near Qianmen. It is said that this is the symbol of Beijing's central axis (meridian).

There is a monument to the people's heroes in the center of the square, and the Great Hall of the People (west) and the National Museum of China (east) are basically symmetrical to the east and west.

1976 after Mao Zedong's death, Chairman Mao's Memorial Hall was built in the former site of Zhonghua Gate.
