This paper adopts post-colonial discourse to explore the "English violence" and the power struggle of "English teaching/ learning" in "Pygmalion" and "My Fair Lady", discussing how Higgins the linguistic professor induces and discriminates the flower girl Eliza. In the process of "teaching" her, the orthodox English is constructed to be a cannon of western empire's hegemony and raises the English-learning anxiety in the disadvantaged. The relationship between the two is like that of the colonizing country and the colonized-a kind of codependence formed in the ambivalence (Homi K. Bhabha) when the two are attracting/ rejecting, mimicking/ mocking each other.
