What are the characteristics of Cang Kejia's later poems?

Cang Kejia's poems pay more attention to the loudness of syllables, the accuracy of words and the appropriateness of metaphors, and pay great attention to scrutiny, which is close to the school of "bitter songs". His poems, taken apart one by one, are like carved handicrafts, which sometimes make people feel that they lack fresh vitality and are not bold enough. Later works, the elegant style of carving has changed, and gradually moved towards simplicity and nature, "broad and vigorous."
