Digital And Chinese Idioms

My paper have three parts which are numbers, idioms and numeral idioms. It argues the meaning of numeral idioms, rhetorical characteristics and the meaning of the numbers in idioms, which includes two aspects---they are "essential meaning" and" abstract meaning". It is issued that rhetorical characteristics are formed in numeral idioms in the ways of "simple and clear way in language" "diversify" and "beauty of structure". This is the identification which is the importance of the numbers in idioms.
