Creative toys are well packaged. Packaging, whether sealing or printing, should be impeccable. Doctor's toys cultivate children's ability of spatial imagination and fine hands-on operation, so as to deepen their rational understanding of time, animals, means of transportation and the shape and color of houses.

Toys can also be natural objects, that is, sand, stone, mud, branches and other non-artificial things. Toys should be understood in a broad sense. They are not limited to things sold in the street for people to play with. Anything that can be played, seen, heard and touched can be called toys.
