Vulgar ancient poems

China's earliest satirical poems include some chapters in The Book of Songs: Rats: "Rats have skins, but people are rude. If a person doesn't look his face squarely, he might as well die. Rats have skin and teeth, but people have no end. A man without virtue should not wait for death. Rats have skins and bodies, but people are rude. If people are rude, Hu will not die? " The sage also cursed: Mencius said: Yang thinks I have no monarch; Mohism loves all and has no father. No father, no king, all animals.
