With the rapid development of China’s economy, both the domestic and foreign trade grows simultaneously．The cosmetic products both at home and abroad catch the eyes of women and men. Meanwhile, various kinds of cosmetic advertisements emerge on TV, internet, newspapers, magazines and etc．These ads promote the cosmetic products and the effect of those products．In order to attract the consumers’ attention, advertisers and producers usually use vague words or expressions to achieve a rhetorical effect．Therefore, it is difficult for the customers to understand the advertisement clearly and roundly. Faced with a large number of cosmetic advertisements, the customers feel hard to make the right product for themselves.
