Xiao Zhou has spent six months running free group purchases in a remote residential community, buying supplies in the early hours, sorting vegetables, and delivering orders. Yet Sister Wang accuses her of secretly making money off the price difference and spreads rumors in the residents' group chat that she sells spoiled produce. After Xiao Zhou publicly presents her purchase receipts, fuel bills, and driving records, she disbands the group and rents a storefront to open her own shop. Her husband uses the experience he gained from sales work to calculate delivery routes and costs, while Xiao Zhou openly publishes prices, product specifications, and after-sales policies. Sister Wang continues filing complaints, claiming the fees are not transparent, while Aunt Zhang contacts wholesaler Mr. Li to cut off Xiao Zhou's supplies. Relying on multiple suppliers, batch records, and community delivery services, Xiao Zhou establishes a foothold and joins forces with nearby small businesses to fight back against exclusive supply agreements.
