The trick lies in market-oriented operation and supervision by parents and schools. Take the high school in red ridge middle school as an example. There are two canteens in the campus, one of which was introduced by the unified bidding of the Municipal Education Bureau, and the other was selected by the Family Planning Commission and the school. Parents and teachers' representatives visited seven or eight large catering enterprises, went into the kitchen and visited the base, and selected the best three enterprises for bidding after on-the-spot investigation. After three procedures, namely, enterprise introduction scheme, defense and judges' tasting, more than 71 members of the whole school and family committees of all grades voted to select the successful catering enterprise.

Not only is the way of introducing canteens innovative, but red ridge middle school also has a set of strict regulations on the later management of canteens. The school has set up a canteen management committee composed of parents, teachers, representatives of trade union members and school doctors. When the canteen is stocked in the morning, the staff of the canteen management committee will ask for the production certificates of all meat and vegetables. School doctors use their own instruments to detect pesticide residues in vegetables and fruits; Before lunch, there will be parents' representatives to check the appearance and taste of the dishes on that day. With such market-oriented operation and strict supervision and inspection, catering enterprises operating canteens dare not be vague, and do their best to provide students with safe and delicious meals every day.

The practice in red ridge middle school has proved that there is no contradiction between safe nutrition and delicious food. As long as competition is properly introduced, parents are completely open and their enthusiasm is fully brought into play, of course, schools should conscientiously fulfill their obligations, so that children can eat well and eat well at school, and it is not difficult to avoid waste.
