Guyuan, the city built in 114 BC, the place where the Silk Road must pass, one of the nine towns in the Ming Dynasty. Well-known attractions in Guyuan include Liupanshan National Forest Park and Huoshizhai. A natural forest landscape, a natural geological landscape. Liupanshan is not unfamiliar to everyone, it is the end of the Red Army's long march. Green trees, streams, flowers and insects give people a feeling of returning to Sichuan. Perhaps for a Sichuanese, there are scenic spots with mountains, water, birds and grasses, which are too common, but for the people of Ningxia, it is really stuffed with Jiangnan. When you take the highway from Yinchuan to Guyuan, you will see the ridiculous hills without a long grass. This strong contrast is enough.
