The maps of Dunhuang and Xining don't look far, but it's very troublesome to walk across Qilian Mountain! There are three lines:

Article 1: Delingha, Chaka Salt Lake, Qinghai Lake and Xining stayed late in Delingha, and crossed Dangjinshan to Dunhuang the next day. The road conditions are good and the road insurance is good.

Article 2: Xining Qilian Zhangye Jiuquan Jiayuguan stayed late in Jiayuguan, and the scenery was the most beautiful after arriving in Dunhuang the next day in July.

Article 3: From Xining to Lanzhou, you can take the train to Jiayuguan or Dunhuang, and there is a shuttle bus. The other two trains are closed!
