Jian'an style refers to the handsome and vigorous style of poetry by the Cao family and his son, the Seven Sons of Jian'an and others during the Han and Wei dynasties.
The literary giants of the late Han Dynasty and the Jian'an period were the "Three Caos" (Cao Cao, Cao Pi, Cao Zhi) and the "Seven Sons" (Kong Rong, Chen Lin, Wang Can, Xu Qian, Ruan Yu, Ying Jun, Liu Zhen) The female poet Cai Yan inherited the realistic tradition of Han Yuefu folk songs, which generally adopt the five-character form. They are famous for their strong character and generous and sad masculinity, forming a unique style of "Jian'an character" in the history of literature, which was later regarded as Respected as a role model. Both the "Cao father and son" and the "Seven Sons of Jian'an" have lived in Heluo for a long time. This refreshing and vigorous style is closely related to Heluo culture. They directly inherited the realistic tradition of Han Yuefu folk songs and set off a poetic climax.
