Zizhou Introduction: Zizhou County is in the north of Shaanxi Province, the hinterland of the hilly and gully region of the Loess Plateau, the southern margin of Yulin City, and the middle reaches of the Dali River. Founded in 1944, it was named after the revolutionary martyrs Li Zizhou. The sub-arid zone between the mid-temperate zone and the warm temperate zone has a continental monsoon climate with an average annual temperature of 9.2 °C, precipitation of 499.1 mm and a frost-free period of 164 days. The Dali River and Huaining River in the county pass through the central and southern parts of the river. The two rivers form the Sichuan River area with low terrain and fertile soil. The two rivers are known as the “rice-grain”. Resources are mainly coal, oil and natural gas. Taizhongyin Railway and Wuding Highway cross the north.
