[0002] Toys refer to objects that can be used for playing. Playing with toys is often used as a way to educate and entertain in human society. Toys can also be natural objects, that is, non-artificial things such as sand, stone, mud, branches, etc.

[0003] Toys should be understood in a broad sense. They are not limited to things sold on the street for people to play with. Anything that can be played with, seen, heard and touched can be called a toy.

[0004] Toys are suitable for children, and are more suitable for young people and middle-aged and elderly people. They are tools to open the skylight of wisdom and make people smart and clever.
