Leshan-Xinjin-Qionglai-Mingshan-Ya 'an-Tian Quan-Lianglukou (Xingou)-Luding-Wasgou-Kangding-Bamei-daofu county-Luhuo-Ganzi County-Manigango (Luolong)-Dege-Gonto. Coming here is considered to be entering Tibetan areas. Next, the troops are divided into several roads and continue to move into Lhasa:
Xiaobei Road: Gangtuo Town-Wala Temple-Jiangda County-Jueyong-Damala Mountain-Changdu County-Enda Village-Leiwuqi-Dingqing Town-Shadingzong-Ya 'ando-Baiga Township-Sanda Bengong-Cuodo Township-Tangpusong, which is also the road often taken by many business travelers and mule gangs. The 18 troops led by Zhang Guohua and Tan Guansan arrived in Lhasa along this route.
Middle Road: Gangtuo Town-Wala Temple-Jiangda County-Jueyong-Damala Mountain-Changdu County-Enda Village-Wahetang-Jiayuqiao-Luolong County-Bianba-Danda Mountain-Chalasondo-Enzhuge Village-Moquka-The 18 advance unit led by Wang of Kerry County is heading for Lhasa along this route.
North Road: Qamdo-Rhonda-Lagon-Nda-Rauqi-Junka-Dingqing-Seza-Insepa-Badasongdo-Yaando-Hoita-Sozon-Nima-Xiaqiuka-Naqu
The overall terrain of this road is relatively high, but it is relatively flat and there are fewer mountains to climb. Most areas west of Dingqing are sparsely populated, but there are many grasslands, which is convenient for releasing horses. So many mule gangs and business travelers are willing to take this road. The first echelon of the 18 Army led by Zhai Jinwu and Yang Jun, the 52nd Division, the154th Regiment, the second echelon of the 18 Army led by Chen Zizhi and Yin Fatang, the 52nd Division, the 52nd Division, the155th Regiment and the Army Artillery Battalion generally take this route. North road is a road, and it is also the official way for the central government of Qing Dynasty to enter Tibet. The whole journey goes straight through the western half of Hengduan Mountain and Nyainqentanglha Mountain, and there are relatively many people along the way, which is often used by officials and people for business travel. The 157 regiment led by Miao Piyi, 53rd Division, originally planned to enter Lhasa along this line.
South Road: Changdu-Bangda-Basu-Bomi-Pailong Natural Danger-Lulang-Linzhi-Lhasa. This road is steep, with dense forests and landslides. Although the altitude is low and the climate is mild, it is difficult to walk and there are few pedestrians, especially those who have walked all the way. Yunnan Army 126 Regiment should have gone to Lhasa via this line, but it didn't leave until Chayu.
In addition, the route for the independent detachment of 18 Army to enter Tibet: Xining-Riyueshan-Daotanghe-Xiangride-the source of the Yellow River-Tongtianhe-Tanggula-Danglaling-Sangrong Township-Nie Rong-Seqing Township-Heihe (Naqu)-Wumatang.
