After Sungpan, it ascends the Min Valley passing Tungpi to Shangleyao, where it crosses the watershed from the Yangtze River side to that of the Hoangho. Thence the line proceeds to Orguseri, and following a branch of the Hoangho to the northwestern turn of its main stream, it proceeds along its right bank via Chahuntsin to Peilelachabu. There it crosses the Hoangho to the northwest turn of the old imperial road, where it joins the Lhasa-Lanchow line and proceeds as far as Lanipar. Then turning northwestward, it proceeds by its own line to Dzunsasak, where it ends by joining the Lanchow-Chochiang line. This line covers a distance of 650 miles.
k. The Ningyuan-Cherchen Line
This line starts from Ningyuan and proceeds in a northwestward direction via Hwaiyuanchen to the Yalungkiang.

From Litang it proceeds in the same direction but follows another road to Kangtu, on the left side of the Kinshakiang. Following the same side of the river, it proceeds to Sawusantusze, where it crosses the Lhasa-Chengtu line. After Sawusantusze, the line continues in the same direction and follows the same side of the Kinshakiang via Tashigompa, to the Huhusair Bridge, where it crosses the Lhasa-Lanchow line. Then following a northern branch of the Kinshakiang to its source and crossing the watershed, it proceeds along the caravan road by Hsinszukiang and Olokung to Cherchen, where it ends, covering a distance of about 1,350 miles. This is the longest line of this system.
