This article discusses and challenges Deng Dun’s view that verbs cannot be used as adjectives. Based on this, it is proposed that humans have the need to express things that are influenced by passive actions or people and animals with certain behaviors, and this expressive need is realized (or projected) in language. Much of this is accomplished through words or structures that describe actions or behaviors to modify and restrict things and people, which is a common principle in human language expression. As for which method to use for expression, different languages use different means of expression (with different parameters), and in Chinese, the expression task is accomplished by using verbs as adjectives to modify nouns.
