This time period can meet the needs of most readers. During most of the day, people usually have enough time to go to the library to read, study or borrow books. Such opening hours can give more people the opportunity to use library resources. For library staff, this time period is also conducive to their work arrangements. They can arrange and borrow books during normal working hours, maintain the order of the library and ensure the smooth operation of the library. Therefore, Datong Library is open at 9:00- 17:00 every day and closed on Mondays.
