Because of the plane in the afternoon, it took only three hours to walk roughly, focusing on visiting the special exhibition hall, mainly because he met an excellent volunteer tour guide, a big boy named Wu Jiehui. His pronunciation was clear, his speaking speed was moderate, his explanations were detailed, plain and easy to understand. Each exhibition hall only selected a few pieces of exhibits to explain, but also lasted for a little and a half. At that time, we all feel that we are still in the mood! Unfortunately, I didn't hear the first half hour's explanation! Entrance can be changed by second-generation ID card, with self-service ticket changer and manual ticket changer counter, and simple security check. Free guides are provided at 10:00 and 14:00 (see Figures 2 and 3 for details).
