On the west side of South Street in Langzhong’s ancient district, the Qin Family Courtyard presents a façade of traditional domestic permanence. Built as a private sanctuary for a wealthy merchant clan, this 1,300-square-meter residence relies on the strict, symmetrical order of a two-entry quadrangle. Its architecture dictates hierarchy and quiet seclusion, with wooden lattice windows and slate floors designed to insulate the family from the bustle of the street.

In April 1935, this architecture of stability became the command center. The Red Fourth Front Army requisitioned the compound, transforming the General Political Department into the nerve center for one of the most precarious operations in Chinese military history: the crossing of the Jialing River.

Visitors walking through the central axis today step into a space where the domestic and the martial once collided. In the rooms where the Qin family likely conducted tea ceremonies or managed ledgers, commanders Xu Xiangqian and Zhang Qinxin spread maps across polished tables, plotting the logistics of moving thousands of troops westward against a formidable natural barrier.

The building preserves this tension between its design and its history. Standing in the main hall, one observes the silence that has returned to the courtyard, a silence that belies the frantic energy of the spring of 1935, when the fate of the Red Army in Sichuan pivoted on the decisions made within these wooden walls.
