We were going to spend 2 hours in this center, but we still had a lot of things we didn't see for3.5 hours. We were so dazzling. For our adults or a 9-year-old, interesting exhibitions followed by one. F1 Racing, Space and Dinosaur Areas are our favorite exhibition areas, and the interactive facilities in the museum are also very attractive. Suggestion: Prepare some thick clothes, which are too air-conditioned. This is a great kids play center with lots of science shows simulations and puzzle games. It's much bigger than you see from the outside and there are lots of interactive projects. It's easy to play here for2-3 hours.
