Zhaoxian County, located in Shijiazhuang City, Hebei Province, is 50 kilometers away from Shijiazhuang City by car. The traffic is inconvenient. It is recommended to drive by oneself. To be fair, the small environment of Zhaozhou Bridge is well built. It crosses the river and forms a very comfortable small park around it. The bridge was built in the Sui Dynasty and was made of stone. The builder, Li Chun, was also a famous craftsman at that time. Zhaozhou Bridge, 1400 years ago, is the earliest and most complete single-span open-shoulder stone arch bridge preserved so far. I learned it in textbooks when I was a child, and I was deeply impressed. It belongs to one of the places that I must go to in my life.
