There is a tradition, that after classes, students remain at school to clean it. At the end of the day, students spend about 15 minutes vacuuming, sweeping, and cleaning various spaces in the school. It is believed that it helps to promote students' understanding of life skills such as personal responsibility. It is also an opportunity to engage with other students that are not classmates and spend time with teachers in a less formal environment. Students become aware of cleanliness and don‘t make such a mess in the first place because they know they'll have to clean it themselves. Just 15 minutes a day have a huge impact so that a child will grow up into a more responsible and respectful adult.
