A man bought a big cat, called him a good pit twice, and caught a mouse for a little mouse, and the master was afraid of the ghost, and said, " The big rats spoil the grain, the little mice spoil the grain, and it is a little mouse, and it is not comparable to the contribution of the big mouse, and you can only eat this.The next day, there was a mouse to steal the cat, and he really didn't use it, and he raised it on the bridge and waited for the mice to eat and grow fat, and the cat caught him to see his master. The guy ate half a pot of food.The master saw that the mouse was bigger than the big cat, and the food was so much, so glad that he gave him two big fish and encouraged to say that your contribution was too big. I hope you catch more rats like this.Just look at the surface results, not the actual effect of the idiot? How much grain do you have to feed my mice?The master thought he was very clever and did not know he was doing something stupid, and the cat raised the mouse with food, and gave it to him, and it looked like he was caught in big mice and grain. Just look at the interests of the eye, and in the end, there are a lot of people who have lost their lives, and we can't do that.We don't want to be like the one in the story, the cat is as confused as the cat, and we need to know what's good and what history is bad, and that's what this story tells us.
