I have time to bring my children here to play in a very good place. It is free to enter the museum. You don’t need to make an appointment in advance, but remember to bring your ID card to enter. The facilities are very clean and the space is large. It can’t be said that there are many people, but if you want to play vr or 5D movies, It is best to go on weekdays, there are not many people, there are toilets on each floor, and there are rest areas. Very user-friendly, all barrier-free facilities, any crowd can visit at will, the government is doing a good job
