We found that【You+N】structure which can be modified by the degree adverb satisfies Property Expression`s semantic, functional, and formal features: Semantically, (Hen)【You+N】is different from the general【You+ N】structure which denotes possession, it indicates the meaning of the property; Functionally, this construction describes Property Subject as a whole; Formally, it can be appear after the BI, and used in the comparison sentence. Therefore, this paper presents that (Hen)【You+N】construction is a syntactic means for Property Expression in modern Chinese. (Hen)【You+N】forms 【PROPERTY VALUE + PROPERTY DOMAIN】structure, thus obtain attribute meaning. VALUE and HUMAN PROPENSITY are huge semantic categories in attribute meaning. Languages with the strong means of word formation like English, can construct adjectives by affixes to denote VALUE and HUMAN PROPENSITY. However, the Chinese language lacks these productive means of word formation, so it is mainly supplemented by syntactic means to express meaning of VALUE and HUMAN PROPENSITY. (Hen)【You+N】is the basic means of expressing the meaning of property on VALUE and HUMAN PROPENSITY in Chinese at the syntactic level.
