Haohai Cube is especially suitable for parents and children or couples. The biggest thing in the world is the viewing window and diving. Although I haven't found out where the diving experience is at last, there is an ice rink in the coastal city of Haohai Cube. Um, it's not expensive to pay 10 yuan or 20 yuan for a person's service fee. Then, if you are hungry, you can go out and choose a restaurant to eat a little to replenish your energy and then go to the next floor. In the Haohai Cube, if there are many animals on the first or third floors, they are mostly marine animals. If there are some land animals on the fourth floor, if they are particularly interested in marine animals or land animals, they can go somewhere. Basically, it's no problem to spend two or three hours.
