The fairy tale "The Partnership of Cat and Mouse" tells readers: You should distinguish the truth before you associate with people. Don't be like a mouse, knowing clearly that you and the cat are natural enemies, and easily believing the cat's words and living in partnership with the cat, and finally losing your life. But you can't cheat others like a cat.
The Partnership between Cat and Mouse is a fairy tale in Grimm's fairy tales, which was collected, sorted and processed by jacob green and william green brothers. Because of their similar interests and experiences, the two men cooperated in studying linguistics and collecting folk fairy tales, so they were called "Brothers Grimm".
