Lin Xiaoyun is the property manager of the Yangguangli neighborhood. Five years ago, she advanced the rent to help Wang Lijuan open the Wangjie Vegetable Store, and personally went door-to-door to secure orders from one hundred and fifty households in the neighborhood. However, over a single scallion, Wang Lijuan publicly slammed the vegetable down onto the ground and hurled abuses at Lin Xiaoyun. Driven past her breaking point, Lin Xiaoyun announced in the homeowners' group chat that their designated partnership was canceled, and introduced the Xiaozhou Vegetable Store as a convenient direct-supply point. To protect her exclusive business, Wang Lijuan relentlessly resorted to tactics such as selling low-priced rotten vegetables, short-changing weights, publicly slandering and spreading rumors, and even purchasing industrial preservatives lacking three certificates to soak and continue selling spoiled vegetables, while falsely accusing Lin Xiaoyun of taking kickbacks.
