Yuefu poetry, the Book of Songs, Chuci and Tang poetry are all ancient poems. The style of classical poetry is handed down from the previous generation, so it is also called archaism. It has three carriers: songs, lines and intonation. Classical poetry is free in meter, without antithesis, even in level, wide in rhyme and unlimited in length. There are four words, five words, six words, seven words and miscellaneous sentences. The forms and styles of Tang poetry are colorful and innovative. It not only inherited the tradition of Han and Wei folk songs and Yuefu, but also greatly developed the singing style. It pushed the artistic features of China's classical poetry, such as harmonious syllables and refined words, to an unprecedented height, and found a typical form for ancient lyric poetry. Tang poetry marks the peak of China's classical poetry.
