At school, students often pay attention to the cleanliness of the classroom. This is not a new problem. We need to clean the classroom, wipe the tables and chairs, throw the trash in the bin, and clean the school regularly. These actions not only help keep the classroom clean and beautiful, but also help train students' sense of self-discipline and work-consciousness. Therefore, we need to pay attention to promoting self-discipline and maintaining classroom hygiene in each student. I promise to keep and keep the classroom clean.
