By the end of Han Dynasty, the poets in Jian 'an began to carry out a series of transformations on Yuefu, including: Three Cao, Seven Zi in Jian 'an, etc. Isn't there a famous saying by Li Bai that "the bones of great writers are all your brushes, and I am Xiao Erxie who grew up beside you"? After the transformation of literati, Yuefu also tended to be in the form of neat five words. Even Cao Pi wrote a standard seven-character ancient poem Ge Yanxing. Later Zuo Si, Ruan Ji and Tao Yuanming also made great contributions to five-character poems. Poetry creation in Wei, Jin, Southern and Northern Dynasties can be divided into literati poems and expensive poems. The formation of five-character poetry meter, or modern poetry meter, is mainly the efforts of your poet. Your poet began to work hard on form. At this time, some poems began to exist independently of music. Gui You's representative poems include Taikangti, Xuanyan and Yuanjia, which finally reached the eternal style and began the transition from ancient poetry to modern poetry. The representative of Yongming poet is "Eight Friends of Jingling", who are some good friends around Jingling Wang. Eight Friends is famous for Xie Tiao, and Xiao Xie refers to him in the sentence just quoted by Li Bai. And Shen Yue. The theory of "four tones and eight diseases" was first put forward in Shen Yue, that is to say, before that, what was basically written like poetry was recognized by everyone, and there was no distinction between high and low. How to rhyme harmoniously, those excellent works of ancient poetry handed down from ancient times are revealed by the genius of the ancients in an unconscious state. Poetry formed an atmosphere in Wei and Jin Dynasties, which is equivalent to the mainstream entertainment activities now, so it began, such as limited time competitions and limited topics. This further prompted Yongming poets to work hard on rhythm and form. Five-character poetry has reached a relatively mature stage. Let's talk about rhyme again. At first, it was spoken rhyme. Before the Han dynasty, the rhyme was very wide, and it was basically enough to read smoothly. During the Six Dynasties, the requirements for meter and rhyme were strict. There were some private rhymes in the Six Dynasties, but poets basically pledged according to their own preferences and did not buy these rhymes.
In the Sui Dynasty, Qieyun was published as an official book, which is now known as the embryonic form of Pingshuiyun. The rhyme book has been revised several times, forming the current horizontal rhyme. Back in Wuyan, Yongming-style poetry came to the early Tang Dynasty after the further development of Palace-style poetry. In the early Tang Dynasty, palace poems were mainly used. As the name implies, they all wrote things like debauchery, dogs and horses, with gorgeous words and beautiful rhymes. Li Shimin, Emperor Taizong, was good at palace poems, and his favorite Shanggongyi and later Shangguan Waner were also masters of palace poems. Some poets began to consciously regulate the creation of five-character poems from the height of creative theory. Song and Shen Quanqi put forward the metrical theory of "recalling sounds and restricting sentences", which basically completed the stereotyped work of modern poetry-metrical poetry. They had a great influence in the early Tang Dynasty, and the Five Laws were widely sought after by scholars in the early Tang Dynasty.
