If children are interested, they can definitely play for half a day, but because the exhibition hall is not big, only three floors, it cannot last a whole day.
We slept until we woke up naturally and entered the museum at 1 pm. It was enough for one afternoon. There are basically two floors. The third floor is for sharing lectures and other activities.
It doesn’t take a day inside, just a little more than half a day. After visiting the Natural History Museum, you can also go to the surrounding areas to see the zoo.
The Beijing Museum of Natural History is almost half a year away. You can go to the Museum of Natural History early in the morning, visit several exhibition halls, eat nearby at noon, and go shopping in the afternoon.
