Idioms are gems of a language which have been refined through ages of use. Idioms are thus always rich in cultural connotation and national flavor. Lots of cultural information is embedded in idioms. Language is a part of culture. Language is the important carrier of culture. Language and culture have close relationship with each other. The study of the relationship between language and culture has been considered a subject of great value. Owing to this, translation theorists and translators have put more attention to the cultural barriers that exist in translation. Therefore, translators have to better understand the relationship between language and culture and the relationship between culture and translation so as to render idioms from the SL into the TL faithfully and effectively.
