Longyou includes Tianshui, Gangu, Wushan, Minxian, Longxi and Lintao. Longyou is a population and grain-producing area, and also the birthplace of the Qin Dynasty, and the birthplace of the Tang Dynasty is Longyou. In addition, the occupation of Bashu in the north and Bashu in the south can not only make Mazhuang soldiers self-sufficient, but also provide a strong strategic buffer for Guanzhong. In the east is Hangu Pass, which can be attacked and retreated, and in the middle is what we habitually call Qinchuan.
