The opening time of Qinghai Museum is from 9:00 to 16:00, but don't think it's really closed at 4:00 p.m. In fact, it's only 4:00 p.m. that no new visitors are allowed to enter, and the museum really closes at 5:00 p.m. The museum is rich and interesting. It takes about 2 - 3 hours to visit. Free tickets are required to enter the museum with ID cards.
