Corridor is the passage of life. The trash can is in the corridor. In the event of an emergency fire safety incident, the trash can is an important safety hazard that hinders escape;

Secondly, put trash cans in the corridor. The weather in Chongqing is hot in summer, and the garbage stinks easily, which breeds mosquitoes and affects environmental sanitation. Especially in this year's epidemic, it is very important to keep a clean and tidy living environment;

In addition, garbage sorting is the obligation of every resident. So how do we trace the source? Who sorted the garbage? Who doesn't have garbage sorting? Street and community workers publicize the knowledge of garbage classification to residents one by one and tell them how to correctly classify and place garbage. After unloading the trash can, everyone will concentrate on sorting and put the garbage in. At the same time, our classification guidance teacher gives fixed-point guidance in the morning and evening rush hours, guiding residents to classify and reduce garbage from the source, and gradually forming a habit. If the garbage bins are not removed, the classified transportation of garbage can not be effectively guided and supervised, and the classification of garbage is empty talk, which is difficult to really implement.
