Yùmén

This location corresponds to Chijin in the Yumen area of Gansu's Hexi Corridor, west of Jiayuguan. In 1404 the Ming court established the Chijin Mongol thousand-household post after Talini and his followers submitted; in 1410 it was raised to a guard. It was one of the frontier guards through which Ming authorities maintained relationships with groups beyond the pass. In the sixteenth century conflict with the Turpan Khanate brought the abandonment of the guard and the movement of its people toward Suzhou. Under the Qing, the area was reorganized, and in 1759 the former Jingni and Chijin guards were combined as Yumen County. This local history should be distinguished from the ancient Yumen Pass farther west.
