What is 5S management of university dormitory?

The so-called "5S" refers to the abbreviations of five words: Seiri, Seiton, Seiso, Seikeetsu and Shit- suke. Because the first letter of romanization of these five words in Japanese is "S", it is called "5S" for short, which is developed for sorting out, rectifying and improving. The ultimate goal of introducing 5S management into students' dormitory is to let students develop good living habits and keep the dormitory clean and tidy.
