Cycling southward from Tianqiao South Street to Zhushikou, turning to Zhushikou East Street, and then continuing going southward along Qianmen East Road, with a total cycling distance of about 2.5 kilometers, you can arrive at the Zhengyangmen Gate.
The Zhengyang Gate, commonly known as Qianmen, is the main entrance to the inner city of Beijing in the Ming and Qing dynasties, with a history of more than 500 years. Among the gates of Beijing, the Zhengyang Gate is the most ceremonious in regulation, which is not only the embodiment of urban layout, military defense, etiquette system and architectural art in the late feudal society of China, but also an important carrier of the history and culture of old Beijing. The Zhengyang Gate is composed of the enceinte and archery tower in the south and the main building in the north, which is an important symbol of the southern Central Axis.
