"Qingyun Lu of a Poor Family" is an epic historical novel set in the Wei and Jin Dynasties. It tells the story of Lu Yunshen, a scholar from a poor family, who relied on his talent, courage and strategy to grow from an orphan in Taiyuan to a famous general in the Northern Expedition, and ultimately promoted social change under the nine-level Zhongzheng system monopolized by powerful families. The story begins in the Yongjia period of the Western Jin Dynasty. Lu Yunshen, a poor man from Taiyuan, died unjustly because his father was framed by a powerful family, and his family fell into ruin. Carrying his father's posthumous scroll "Mao's Poems" and a paper knife, he went to Luoyang to study alone. He suffered humiliation in the prestigious school, but he formed a "blood-oathed seven sons" alliance with Han Jizi, Gu Wenruo and other poor disciples. After the outbreak of the Eight Kings Rebellion, he followed Sima Rui, King of Langya, to the south to Jiankang, where he dealt with Wang Dao, Yu Liang, Huan Wen and other Jiangdong sects to form the "Beifu Hanshi Camp" and made extraordinary achievements in the Battle of Feishui. However, after becoming famous, he faced a deeper dilemma: Will he become a new powerful family after taking power? Was the Northern Expedition just to drive away the barbarians, or was it to break the long-standing abuses of the millennium-old system?
