Therefore, a string of ears of grain is carved in the cave of Wengchengmen, and there is an endless stream of grain trucks coming and going during the filling festival in Kyoto. "Chaoyang Gusui" was the first person to meet the gods when the grain was transported from the south to the north. Grain truck. In the past, there was no railway traffic. Grain produced in the south must be transported by water to Tongzhou (now Tongxian) in the east of Beijing.

In addition, Chongwenmen's heavy tax clearance also makes foreign businessmen daunting. The name "Chongwen Iron Turtle" resounded throughout Kyoto. Take a wine cart, and the wine road is outside the city. Most of the fine wines of that year were shipped from Zhuozhou, Hebei and other places, so it is natural to take the south road when entering Beijing.

Zhengyangmen, formerly known as Li Zhengmen, is commonly known as the "front door" in Beijing, echoing the north and south of Di 'anmen (commonly known as the back door). Wengcheng Guandi Temple is the first of the nine gates, so it is called "Zhengyang Guandi".
