"Repeat, will fall on the ground to walk. Although you are sensitive, there is nothing you can do. " Su Shi, a writer in the Northern Song Dynasty, wrote Fu on the Mouse. Rat Fu is an allegorical poem about objects. The author described the story of a sly mouse playing dead and running away. "If you repeat, you will fall to the ground. Although you are very sensitive, you won't be caught off guard ",which means that you put the empty food bag face down and want to dump the dead mice inside." Who knows that it suddenly ran away as soon as it landed, even the agile people would be caught off guard. Su Shi contradicts the traditional morality of mice in his literary works, and writes that mice "bite instead of bite, and cause people with sound;" Die first, then die, and seek to divide it by shape, so that people who are the spirit of all things are deceived by it.
