In the afternoon, I went at one or two o'clock and played until 5:30. It seems that I can't enter the venue at five o'clock. I only watched space travel. But I feel that the Chinese science and education film is played in the spherical shadow hall. There are many exhibition halls, not too many people, most of them are children. Many need to practice. There are not many people, so there is no need to line up. The dinosaurs are so realistic. The involved are also very wide. Good service attitude.
