From the acceptance of criticized objects approaching the literary criticism of Qin and Han Dynasties

There was confused ideas about the limits of literature and non-literature between Qin and Han Dynasties. As the historical and classical works, the Book of Songs was treated as the textbook and the universal truth. So there was still no genuine literary criticism in Qin Dynasty. With the scholars and the creation of literature constantly emerging, the scope of criticized objects was extended and the relatively unattached criticism texts came out. The literary criticism gained a basic meaning, that was to pay close attention to works of literature and writers.
