Янь Фу
Yan stated in the preface to his translation of "Evolution and Ethics" () that "there are three difficulties in translation: faithfulness, expressiveness, and elegance" (). He did not set them as general standards for translation and did not say that they were independent of each other. However, since the publication of that work, the phrase "faithfulness, expressiveness, and elegance" has been attributed to Yan Fu as a standard for any good translation and has become a cliché in Chinese academic circles, giving rise to numerous debates and theses. Some scholars argue that this dictum actually derived from Scottish theoretician of translation, Alexander Fraser Tytler.
