Dinosaur Park was visited the next day before returning to Shanghai. Ticket-free online tickets can be booked, of course, if it is not the peak, you can get tickets on the spot. I happened to run into a system problem when I went there, so I went directly into the library without brushing my ID card. On the left is the main entrance of the first floor of the third floor. On the right is the Museum and Museum. On the first floor is the temporary exhibition hall. On the second floor is the Changzhou History Station. The third floor is the legendary Children's Natural Museum. Children's commentator (a bright spot) but the exhibits really can't compare with the Shanghai Museum of Natural History. If you have any expectations, you can visit them for 1-2 hours.
