As we all know, the existing of language is not far from the cultural, the two functions are intimately linked.Advertising, as a kind of cultural phenomenon,it inevitably will play on the marks of different cultures.For example,China has a kind of wine called Du Kang.When chinese people see the identity of Du Kang, it will remind them of the inventor and the good liquor.So it is common that when the company publicize the wine, they always translate it into Du Kung.To a native English, it won't be have connection in the mind because they haven't the same cultural background and it is not done smoothly the communicative intention.According to the relevance, this translation is irrelevant to the subject and not to mention meet the optimal relevance.But if we translate it into Du Kung -Chinese Baeehus, westerners will show the same reaction as well aschinese see the mark of Du Kang. It is much easier to remind the westerners of goo liquor for the name Baeehus, it is the name of Dionysus in the Greek mythology.In this way webulid the optimal relevance.The original language and the target language has beenestablished a full contextual effect between audiences.And also the advocates are successfulto express the information to the target audiences from the originl language.
