Language is an important carrier of culture, and culture finds a better representation through language use. As Sapir-Whorf Hypothesis holds that there is a correlation between language and culture, different nations have different cultural backgrounds, which means that their ways of showing politeness are not the same. And this kind of difference will definitely be embodied in language. Politeness principles can apply to all languages, but it may have different representations in different cultures. Recognizing these differences may help us improve intercultural communication and behave more polite in intercultural communication.
