　　Chinese Idioms Chinese idioms refer to comprehensive and integrated fixed phrases and expressions. Idioms are established and accepted by constant usage and common practice. An idiom is a language unit that is larger than a word, but has the same grammatical function as a word. Most Chinese idioms consist of four characters. For example, ziqiangbuxi ( make unremitting efforts to improve oneself), qingchuyulan(bluer than indigo), and houjibofa (success comes with time and effort). Idioms are extrated from folk proverbs, ancient works of literature, poems, fables, allusions, and well-known sayings. Idioms are a part of the Chinese language that are concise and have great vitality.
