The so-called "four masters in the early Tang Dynasty" refers to Yang Jiong, Lu, Luo. Their social status is relatively low, but they are brilliant. During the pioneering period of Tang poetry, they tried to get rid of the ups and downs of the Southern Dynasties' poetic style, actively explored the theme of poetry, and made new explorations in the form of poetic meter. Lu and Luo's seven-character rhythmic poems created a new artistic conception on the basis of palace-style poems, which made palace-style poems move from the palace to the market, and they were reformers of palace-style poems. Five-character verse developed into stereotyped writing of Wang and Yang Caiji, and moved from Taige to the desert beyond the Great Wall in their hands. They were the founders of five-character verse.

Lu's The Ancient Meaning of Chang 'an, Luo's The Forbidden City, Wang Tengting's Poems, Biography of Being Sent to Shu, and Yang Jiong's Joining the Army are all typical representatives.
