Abstract: It is not without reason when Feng Jicai criticised Lu Xun in 2000.Feng's Criticism of Lu Xun originated from Liu He's theory of national spirit mythology.Liu he held that Lu Xun's national spitrit theory was influenced by the American missionary Ming Enpu's theory of colonialist hegemomy.Consequently,Liu totally negated the existence of the Chinese people's deep-rooted bad habits.This paper gives a systematic repudiation to Liu He's post modern approaches and post colonial views,positively expounds on the historical rationality of Ming Enpu's writings,and reaffirms the validity of Lu Xun's criticism upon the deep-rooted bad habits of the chinese people.

Key words: Lu Xun, post colonial theory, national spirit face, Ah Q's theory
