Abstract: The corvee servicemen of the Altai military stations along the post roads from Zhangjiakou to Uliastai could be classified as two types: the formal service members and auxiliary privates． The latter could be divided into Policemen and Auxiliary Policemen． The difference between the formal service members and auxiliary privates could be seen from their verified statuses，different treatment，and uneven duties． After the Tongzhi reign，it was common for the auxiliary privates to rebel against their heavy labor duties．There were some attempts by authorities to deal with them but with little success． During the Guangxu reign，the princes of Qalq-a Mongolia also had tried to cope with these problems through the reform of the military stations service system but the reform ultimately failed．
