At the same time, he cultivated farmland extensively in the north and built water conservancy projects, which played a certain role in the restoration of agricultural production at that time. Cao Cao was proficient in the art of war and wrote books such as "Sun Tzu's Brief Interpretation", "The Art of War" and "Meng De's New Book".

Cao Xueqin (1715～1763) was a novelist in the Qing Dynasty. The name is Zhan (zhan), the courtesy name is Mengruan, and the names are Xueqin, Qinpu and Qinxi. His ancestors were originally Han people and later became the "wrapper" of Zhengbai Banner in Manchuria. During the Kangxi period, starting from great-grandfather Cao Xi, three generations and four people inherited Jiangning weaving for 60 years, becoming a prominent aristocratic family. Later, due to the fierce internal struggle in the Qing palace, his father was implicated, convicted and demoted from his official position, his family property was confiscated, and his family gradually declined. Cao Xueqin's life coincided with the period when the Cao family was in decline. Cao Xueqin moved to the western suburbs of Beijing in his later years and lived in even greater poverty. When his youngest son died in 1762, Cao Xueqin was so heartbroken that he fell ill. He finally died on February 12, 1763 due to poverty and illness without medical treatment (some say he died in 1764).
