Why do some people think that Rubik's Cube is a childish toy for children?

The Rubik's Cube was invented in 1974. When it was popular in China, it was when parents were children. So now my parents' generation will think that children play.

Actually, there is no need to explain. Since some people say that it is a child's toy, let him recover it once, and 100% can't be recovered, then he will definitely say that he will recover it that year. Obviously, he is lying. According to what he said at the time, tell him to try to save it. Since he just started cursing you, if he can't spell it, you can't let him step down.
