It is rather surprising that we often come across immoral literary taste in the poetry, chiefly anonymous, of the Han Wei period. It shows itself in calumnies against the effort that everybody should make or against moral feelings, in a comparative description between one's former and present wives, in unsympathetic words on the death of one's friend, and in many other instances of a similar vein. Such immoral literary taste, unknown in Shih Ching (詩経) , is traced back in poetry to early songs and poems.
