Why does The Citizen of the World use a Chinese traveler as its narrator?

In The Citizen of the World, Oliver Goldsmith employs the narrative device of a Chinese traveler to provide a fresh, external perspective on British society. By framing the work as a series of letters written by an "Oriental" visitor to London, Goldsmith is able to satirize Western customs and social norms through the eyes of an outsider who comments on his experiences both tolerantly and shrewdly. This literary technique allows the author to critique the human predicament and the peculiarities of 18th-century English life from a detached, observant, and often ironic vantage point.12
