Can anyone tell me the routes of the two Silk Roads from Gansu to Xinjiang? What cities did you pass through? What are the tourist attractions? The more detailed, the better. thank you

① The northern line runs from Chang 'an along Weihe River to Guo County (now Baoji), across Zhangxian County (now Longxian County), across Liupanshan Mountain, along Zuli River and across Jingyuan Yellow River to Guzang (now Wuwei), which is an early route with short journey and poor supply conditions along the way.

② The southern line runs from Chang 'an along the Weihe River to Longguan, Shangguan (now water), Didao (now Lintao) and Bao Han (now Hezhou), from Yongjing to the Yellow River, passing through Xining and Dou Gu (now Ferry) to Zhangye.

(3) The central line and the southern line separate in Gao Shan, cross Longshan, reach Jincheng County (now Lanzhou), cross the Yellow River, return to Zhuanglang River, and turn Wushaoling to Guzang. Although the southern line has good supply conditions, the detour is long, so the central line later became the main line.

After the North-South Central Line meets, it goes from Zhangye to Dunhuang via Jiuquan and Guazhou. The middle part. Dunhuang to Congling (now Pamirs) or Pilars (now drepung monastery).
