Translation involves language as well as culture. Cultural similarities exist in languages; however cultural differences have an essential bearing upon translation. Even approximate equivalent and loan words have different implications and usages in English and Chinese. So, this challenges the traditional concept of equivalence as a constitutive feature of translation. To an author, there is no such thing as absolute equivalence in the context of E-C translation for the simple reason that Chinese and English belong to two entirely different cultural traditions. However, through careful comparative studies, relative equivalents can be achieved.
