The forms and styles of Tang poetry are rich and colorful, bringing forth the old and bringing forth the new. It not only inherited the tradition of Han and Wei folk songs and Yuefu, but also greatly developed the singing style. It not only inherited the five-character or seven-character ancient poems of the previous generation, but also developed into a long and huge system of narrative romance; It not only expanded the use of five-character and seven-character styles, but also created modern poems with particularly beautiful and neat styles. Modern poetry was a new style of poetry at that time, and its emergence and maturity was an important event in the history of Tang poetry development. It pushed the artistic features of China's ancient poems with harmonious syllables and refined words to an unprecedented height, and found a typical form for ancient lyric poetry, which has been especially loved by people so far.
