The focus of this question is whether you are talking about Baoji City or Baoji County (now chencang district). The level is different, and the name should be analyzed according to the situation at that time. Before the Republic of China, the western part of Guanzhong was always in Fengxiang, so ancient Baoji was just a county, covering the present Baoji urban area and most of chencang district. The appellations in the Tang Dynasty are also changeable, as follows: in the first year of Tang Wude (6 18), Changshe County was established in the east of the southern county, changed to Wushan County in the first year of Zhenguan (627), changed to Wushan County in the second year of Shangyuan (76 1) and later renamed Wushan County. In the third year of Yuanhe (808), he withdrew from Nanyou County and merged into Wushan County. In the seventh year of Zhenguan (633), Guo County was merged into Qishan County, and in the second year of Tiancai (69 1), Qishan County was rebuilt. In the second year of Zhide (757), on February 15th, Chencang County was renamed Fengxiang County, and on 18th, it was renamed Baoji County because Chencang Mountain was blessed with crowing. In the Tang Dynasty, Guo County and Baoji County were under the jurisdiction of Fengxiang House. Wushan county and the south are under the jurisdiction of Longzhou county. —— Fufeng Shi Hao is amazing in the world and moving in emotion.
