@cuonglm There is no reason to explain 834 differences between shell and find to an user that is asking a very very basic question. At the basic level both share the same Notation.
That's why a find pattern should be quoted to avoid it being interpreted by the shell.
And to be honest: You really struggle using English, there is no reasonable sense that I can extract from your last words. It would be better if you stay away from any attempt of explaining language use to me.
