In Beijing, there is such a "line" that connects the Bell and Drum Tower, the Forbidden City, and Yongding Gate. It is a great creation of Chinese civilization in urban planning and construction; After more than seven centuries of vicissitudes in Yuan, Ming, Qing and modern times, it is the soul and backbone of the old city of Beijing...it is the central axis of Beijing.

Liang Sicheng, a famous architect, once said: "Beijing's unique and magnificent order is produced by the establishment of this central axis." One line leads to one city, and one city meets one line. Let us unlock the historical time and feel the temperature behind it.
