In 1985, Wucheng, a prefecture-level city in the south, was in the early stages of reform and opening up, with the rise of self-employed businesses and wholesale markets, the collision of old and new ideas, and the poor flow of information. The "Sanduo Alley" in the old city gathers antique stalls, food stamp sellers, and small businessmen, while the emerging "Fumin Building Materials Market" is a gathering place for households worth ten thousand yuan, providing a natural soil for Qianmen to do business. At this time, the definition of "speculation" in the policy was vague, and there were loopholes in supervision, which became a hotbed for thousands of activities.
