Han Yu attaches great importance to the art of language, which is related to his concept of "thinking about words". He once advocated "words must come from words", "acting according to facts" and "acting according to words", and only the ingenious language can achieve Ming Dow's goal. His prose language is concise and vivid, accurate and vivid, fluent and changeable, creative and expressive. Han Yu's articles are rich in vocabulary, good at absorbing ancient words, using contemporary languages and casting them into quaint and novel languages. Many of his novel sentences are still circulating today, such as "grinning", "chasing dogs", "being criticized at every turn", "kowtowing", "crying when you have grievances", "the law of the jungle" and "learning from a painful experience". The syntax of his articles is mainly free and changeable single-line loose sentences, and he often deliberately uses some parallel prose syntax.
