随着中央王朝势力向西藏地区的延伸,藏事日繁,川藏线成为沟通内地与西藏联系的重要通道。为保证官员、军队出入和物资运输、信息流通等的顺畅,清政府在康区入藏沿线安设了不少来自四川绿营的塘汛驻军。 With the extension of the Central Government’s forces to the Tibet region, Tibetans have a long history of possession, and Sichuan-Tibet line has become an important channel for communication between the Mainland and Tibet. In order to ensure the smooth flow of officials, troops, materials and transportation, and information flow, the Qing government set up a large number of Tongxun garrisons from the Sichuan Green Camp along the Tibet Autonomous Region into Tibet.
