Guanjiaoshan Tunnel and Delingha along the Qinghai-Tibet Railway.

After passing through gangcha county, I gradually left the pasture around Qinghai Lake, went to Haixi Mongolian and Tibetan Autonomous Prefecture, and then passed the Guanjiaoshan Tunnel, the highest altitude tunnel in Xining-Golmud section of Qinghai-Tibet Railway, with an altitude of 3,690 meters. Before the completion of the Golmud-Lhasa section of the Qinghai-Tibet Railway, I once passed through the Guanjiaoshan Tunnel, the highest tunnel in China. The vegetation was more sparse, and the Gobi scenery was faintly visible. When I came to Wulan County, a large area of farmland appeared. The buildings in the county town are very similar to those in the countryside around Xining. After crossing Wulan County, it has been accompanied by the 3 15 National Road of the railway, and it has been separated to the next stop, Delingha City, which is 530 kilometers away from Xining and 387 kilometers away from Golmud in the west, with an altitude of 2,982 meters. Delingha is Mongolian, which means that when golden Yuan Ye approaches Delingha, you can see some small salt lakes in dribs and drabs: Keke Salt Lake Gahai and other Delingha are liberated. There are only more than 40 families, and the train with more than 65438+100000 livestock is approaching the urban area of Delingha, and tens of thousands of hectares of fertile fields and green forest belts can be seen in the suburbs. A tourist attraction in Delingha is Crook Lake and Tuosu Lake, located 40 kilometers west of the city. The Qinghai-Tibet Railway just passes through these two lakes. In summer and autumn, the setting sun shines on the lake, which is colorful and forms a picture with migratory birds living on the island, cattle, sheep and birds foraging on the shore of the lake.
