Public service ads should be translated in a polite manner and should show different measures of politeness as needed.#8217; However, Hu Lianwei (2009) took a different approach. He explored the C-E translation of public service ads from the perspective of pragmatic translation, by taking two key factors of pragmatic language equivalence and social pragmatic equivalent into consideration, he respectively studied the C-E translation of public service ads.
