The Classic of Poetry is the first collection of poems in the history of Chinese literature, marking the break from the primitive state of ancient Chinese literature into a mature period, in which the expression of emotion "poetry speaks of will" became the founding program of Chinese poetry. However, this kind of lyricism is a restrained and limited implicit feeling, which expresses a kind of "neutral" beauty that is compatible with feelings and reasoning, and forms a gentle and generous poetic style, which has become the criticism of literary theories of all times, and has influenced the creation of poems in later times.
