In a bright yellow shop in Xiagang Street, Siming District, Xiamen City, Zhang Xuelan went downstairs to turn on her mobile phone after coaxing her last child to sleep, and then a surveillance video playback appeared on the screen. In the video, several children sit around the table, eating fried beef with cucumber, drinking green vegetables and pork chop soup, with yogurt and seasonal fruits at hand; In the food preparation area at the lower left corner, an aunt put the dishes and chopsticks into the disinfection cabinet, and put raw and cooked food into different refrigerators. The table beside her was as bright and clean as new. "Now parents can see their children's meals through their mobile phones, which is convenient and reassuring." Zhang Xuelan, 44, is the director of this "Best Choice Trusteeship Center". Every day, more than 30 primary school students eat lunch and take a nap here. Parents and children affectionately call this trusteeship model "small table". The "small dining table" tests the wisdom of grassroots governance. "The" small dining table "has been a great help to children and adults." At 8 p.m., Su Lizhou, a citizen, came to a care center to pick up her children. Although her home is only a few kilometers away from the school, she works in an accounting firm and her husband works in a ferry company. They often work overtime. In addition, the elderly at home are ill, so the "small table" at the school gate has become her priority. Five years ahead, it is not easy for parents in Xiamen to find a "reassuring" "small table". "The industry threshold is low, the subject qualification is unknown, and there are blind spots in the supervision..." Lu Jiaxin, deputy director of the Market Supervision Bureau of Siming District, felt deeply about this. The reporter found that until 2017, most parts of the country had not made clear provisions on the standardized management of such subjects; Moreover, as the trusteeship institutions outside primary and secondary schools involve education, health, market management and other departments, the management responsibilities are not clear, and the food safety of the "small dining table" outside the school is difficult to be effectively guaranteed. "If the regulations at that time were strictly followed, the 'small dining table' would be 'closed' without a business license." Rao Manhua, deputy director of the Xiamen Municipal Market Supervision Bureau, said, "But the people have a huge demand for such services, and it is unrealistic to ban them all. At the same time, the" small dining table "outside the school covers a wide range of areas, and it is often overlooked by surprise investigation and treatment, and the effect is not ideal." Through continuous research, Xiamen's market supervision department realized that the "small table" could not be managed by itself, let alone "closed". At the time of difficulty, the management exploration of a community inspired us: Since 2009, Jinjiting Community in Siming District has formulated the Quantitative Form for Assessment and Evaluation of Community Trusteeship Classes to assess the teacher allocation, business space, kitchen equipment and sanitation of the "small dining tables" in the area. "At the end of each year, we will hold a commendation meeting to announce the evaluation results and award the excellent 'small table' medal." Yao Liya, the secretary of Jinjiting Community, said, "Parents recognize this' brand 'very much, which has greatly stimulated the enthusiasm of operators. At the same time, we conduct dynamic management, and take delisting measures if we later find any unqualified behavior." Experience shows that the "small dining table" outside the school can be well managed by paying attention to the establishment of rules and regulations, carefully implementing responsibilities, and combining social co governance. In order to change the wild growth of off campus trusteeship institutions and the situation that there is no regulation to follow, Xiamen Municipal Government
