Generally speaking, we don't check beds, but some schools have their own management committees. For example, there is a boarding club in our school. They usually check their hygiene and bedtime regularly, and sometimes they are accompanied by teachers. That is rare, but if the teacher comes, it is said that the situation is more serious. However, the inspection time is usually from Monday to Friday, and local students can go home and sleep on weekends, as long as they don't delay class time.
