It can not only be used as a teaching aid, but also a toy for children's entertaining, while solving the problem of lack of teaching aids and toys in poor areas.

The well-designed yellow-blue contrasting color scheme improves children's identification and memory efficiency of symbols, and promotes children's visual development.
