Qi Yanchuan returned to his hometown, where his family's small grocery store was facing heavy debt and on the verge of being transferred. Abandoning traditional wholesale routines, he started with small-value essential goods, insisted on strict bookkeeping and goods inspection, and broke the market monopoly of local wholesaler Ma Fugui. Facing price cuts, intercepted goods, and supply barriers set by competitors, Qi Yanchuan united surrounding farmers to establish grading and on-site settlement supply rules, securing long-term orders from factories and restaurants. Overcoming transportation losses, villagers breaking their promises, and severe capital shortages all the way, he started from a small grocery store and built a county-level agricultural and sideline product supply system.
