You can't. Tongzhou Library can't stay any longer. According to the website of Tongzhou Library, Tongzhou Library is open during the day: Tuesday to Sunday at 8: 30- 18: 00, and at night: Tuesday to Sunday 18: 00-22: 00 (night opening is limited to the lobby on the first floor), so it is impossible to stay in it for 24 hours. Tongzhou District Library, located in the south of Tongzhou District Cultural Center, east of Mao Jing Building, Tonghu Street, Tongzhou District, Beijing, covers an area of 1.6 million square meters, nearly three times more than the original library.
