At the intersection of Tongzhi Street and Tsinghua Road, the environment is good and quiet, but if you want to study by yourself, you'd better go early. If you go late, it will be difficult to find a place. It is cool in summer. It opens at 8: 00 am, closes at 3: 00 pm on Wednesdays, at 6: 00 on weekends and holidays, at noon on the last day of each month 12, and at 8: 30 on weekdays.
