In ancient times, mice were originally a kind of spirit in Heaven. Heaven has given him the key to God's barn. But the mouse is not a a value of the information, it be hold the key, feel free to open the warehouse and eat all the rice.After Heaven knows, taking a piercing, not giving it above anymore, but pursuing below the earth to wrongly keep the keys of the world.But what is the disease, the rats invite each other to the rice paddles of the people to eat fully. So much so that one must say:“Where was that old mouse? Now eat my rice like this? "He was bitter, he just called to the King of Kitchen. The King of Kitchen immediately forced it to return to Heaven and said:'' This mouse is a rat of Thien Dinh, why did Thien Dinh drop it on earth? ''Heaven says: ''Yeah, before it up here keep the key of the barn for me. But because it ate my rice clippings so much, I didn't let him up here, I sent him down on earth so he could keep the rice down there.''Kitchen King: ''He went down there and ate very bad rice clums. We thought: The grain of Heaven is much, and the grain of God is little, and the grain of God may not eat it all, but those of them keep eating, in days it ends, and the people starve to death. So please let it go to Heaven now is right.''Heaven heard, said: '' Can not. I chased it away, I can't get it up here again. Now, there is a way: I have a cat, I let you bring it down to earth so that when the rats eat the rice of the world, let the cat let it catch the mouse, then growl and eat the mouse, when will it be? If he did not want to catch the mouse, he told the cat to keep shouting to the mouse: "Poor, poor, poor", the rat was also afraid and had to leave.''The Kitchen King bowed to the barbell, then brought the mouse and the cat back to earth. Then follow the teachings that do.So now, when the cat stalks to catch the mouse, then the cat keeps "growling, growling" and when the cat cannot catch the mouse, the cat sits and says: "poor, poor, poor, poor" ...But at that time, the cat sat back and thought, and got angry with the King of Kitchen, because it was because of the King of Kitchen that cats had to go to earth. But there was nothing to do with the King of Kitchen, the cat had only an occasional way to go in the middle of the ashes to defecate.
