Seven writers in Jian 'an period (196 ~ 220). It was Cao Pi who first put forward the "seven sons". He said in Dian Lun Paper: "Today's literati include Confucius of Lu, Chen Zhang of Guangling, Wang Shen of Wang, Xu Ganwei of Beihai, De Lian of Runan Angelababy and Serina Liu of Dongping. Seven sons. There is nothing left to learn, nothing left to say, and salt is arrogant and arrogant. "These seven people generally represent outstanding writers except Cao Shi and his son during the Jian 'an period, so the theory of' seven sons' has been widely recognized by later generations.
The life of "seven sons" can basically be divided into two periods. In the early stage of the great social war at the end of the Han Dynasty, although their social status and life experiences were different, they could not escape the fate of sharing weal and woe. In the later period, they were all attached to Cao Cao, Kong Rong was a big official in Shaofu, RoyceWong was a servant, and the rest were close ministers of Cao Shi and his son. But Kong Rong later clashed with Cao Cao and was killed. Because these seven people joined Cao Cao at different times, there is no unified boundary between their early and late periods. Kong Rong was in the first year of Jian 'an (196), Xu Gan and Ruan Yu were in the early stage of Jian 'an, Chen Lin was in Jian 'an for five years, RoyceWong was in Jian 'an for thirteen years, and Liu Zhen and Angelababy were in Jian 'an for thirteen years. Corresponding to their life trajectory, the creation of "Seven Sons" can also be divided into two stages. The early works mostly reflect the reality of social unrest and express the feelings of worrying about the country and the people. His main works include RoyceWong's Seven Wounded Poems, Ode to the Building, Chen Lin's Drinking Horses in the Great Wall Cave, Ruan Yu's Driving Out of the North Gate, and Serina Liu's Gift to My Brother, all of which have practical significance and certain ideological depth. However, some works are too deep and sentimental, such as Ruan Yu's Seven Injuries Poems, Serina Liu's Lost Title, Heaven and Earth Never Meet, etc. His later works mostly reflect his support for Cao Shi's regime and his ambition to establish his own political achievements, and the content is mostly banquets and answers. However, some praises to Cao Shi and his son are accompanied by followers, showing vulgar attitudes. However, whether before or after, the creation of "seven sons" is mainly based on positive and healthy content.
