Butterflies are the harvest of our trip to the Museum of Natural Science. It's worth paying us an extra eight yuan ticket. Tickets can be purchased from gift shops, so there is no need to queue outside the museum. I've been to Hainan Tropical Ocean World in Leeds, England, and this is the best place I've ever been to see butterflies. But to be honest, it's really a good place. The butterflies here are more than I could imagine. This place is really worth visiting.
