Take three five or six-year-old children to Tianjin to play, before the children have not been to the museum, but also want to let the children have long insights. Museum passes through security checks and the air conditioning is cool. There are so many people that they bring their children to play. The exhibition hall on the first floor has dinosaurs and can move. There are many exhibition halls on the second floor, including dinosaurs, marine animals, fossils of ancient animals, various kinds of crystals, and a Silk Road exhibition hall. The third floor is a wildlife exhibition. In a hurry of time, we did not go to the third floor and the second floor did not turn completely. But the children were very excited and took it seriously. The museum looks like a big buckled bowl outside. There is a large area of water in front of the main entrance, beside which there is grass. The photographic effect is also good.
