In the quiet of Yingpan Alley, within the core conservation zone of Jianchuan Ancient City, stands a courtyard that once served as the nerve center for a regional revolution. On October 23, 2023, the Dali Bai Autonomous Prefecture designated this site as a prefectural-level cultural relic. It preserves the memory of the Jianchuan People's Self-Defense Force Logistics Department, established in late May 1949.

The story of this building connects directly to the armed uprising of April 2, 1949, organized by the Communist Party of China Western Yunnan Working Committee. Hours later, at 1:00 AM on April 3, a group of 130 fighters gathered at the local Confucian Temple. By 2:00 AM, they slipped through the west and south gates of the county town to overthrow the Kuomintang administration. To overcome their opponents, the fighters used clever deceptions. They set off firecrackers inside metal gasoline drums to mimic the rapid rattle of machine guns, blew military bugles, and swung heavy iron axes to splinter the wooden back doors of the government headquarters. The successful raid yielded eighty rifles, twenty thousand rounds of ammunition, two hundred grenades, and fifty military uniforms.

Following this victory, the regional self-defense force was born. To sustain the frontline fighters, the Western Yunnan Working Committee set up its logistics headquarters in this Yingpan Alley property. Ou Gen, a local Bai intellectual and deputy secretary of the working committee, took charge as director. Inside these rooms, staff managed the storage and transport of grain, weapons, and clothing. Young locals drove the effort. Eighteen-year-old Li Shijun, who had joined the secret Democratic Youth League in 1944 and became a party member in March 1949, returned to his village to serve as party secretary. He mobilized farmers to carry supplies, coordinate pack animals, and deliver rations to the logistics office.

Today, the quiet timber frames of the courtyard carry the memory of these efforts. Visitors can stand where workers once stacked heavy sacks of grain, sorted coarse cotton uniforms, and organized ammunition boxes destined for the mountain trails of western Yunnan.
