Generally, A 5․4 movement period of China is known for the period of historical transposition. Although We call that the literature of this period is neoliterature, I will pay attention to the significant changes of its period. Because, in this period, Polemical dispute is begun and raised between the Tradition and Antitradition. And more importantly, I recognize that A study of modern literature is started from this momentous period. Therefore, deliberating these changes is the main study of the procession from Tradition to Antitradition vice versa. The Doctrine of evolution consists in methods is at the center of these changes. Hushi\'s become an adherent of the Doctrine of Evolution, however, Marx-Lennists follow the other line. Hushi\'s line follows Liang chi-chao. Following him, Hushi says the use of Bai-hua letters in 1917. In fact, The use of Bai-hua letters is originated from Shijing, after by way of Gongan branch of Ming dynesty and Ching dynesty. Therefore, we can say Hushi is the first advocate of the theory of the Baihua letters. The theory of 󰡐the Literature is very often changed following the times󰡑is same as Gongan branch of Ming dynesty. In this point of view, we are reached to the change of cognition. That is, Hushi\'s theory is not Tradition→Antitradition→Tradition but Trdition→Tradition→Tradition as Baihua letters. This means Hushi is not a follower of theory of foreign literature. Therefore, our cognition about Hushi and his theory should be changed.
