Is it better to travel to Zheng Guoqu in rainy days or sunny days?

A sunny day. Because Zheng Guoqu is an outdoor scenic spot, it is difficult to ensure the safety of witnesses in rainy days, and it also affects the experience of tourists, so it is generally closed in rainy days. Zheng Guoqu, located in Shaanxi Province, was built in the Qin Dynasty, which is the earliest large-scale water conservancy project in Guanzhong. In 246 BC, Zheng Guo, a Korean water conservancy engineer, presided over the construction of Zheng Guoqu in Qin State, which lasted for ten years. After its completion, it was named Zheng Guoqu after a water conservancy engineer.
