When it rains heavily and there is no place to go, we must go to the underwater world. The ticket price is cheap, and we just catch up with the activity. We make gifts for our tasks. All of a sudden, our children's interests are aroused. The staff gave us a piece of paper with all kinds of marine creatures on it, so that all the children can find it, paste it on, and complete the task to exchange gifts at the gate. This activity is really superb. Help the children to have a deeper understanding of submarine organisms. Okay.
