Cao Xueqin (17 13- 1763, 1724- 1764) is a novelist in Qing Dynasty. Name Zhan,no. Xueqin, piano score, My ancestral home is Liaoyang. Manchu. China, a native of Qing Dynasty, is generally regarded as the author of China's famous novel A Dream of Red Mansions. He comes from a big bureaucratic landlord family with a "century-old family", and his grandfather's uncle has inherited Jiangning weaving for three generations for 60 years. Later, his father was implicated in the incident and was removed from his post. The decline of family fortune made Cao Xueqin suffer the bitterness of life. In the last decades of his life, he created A Dream of Red Mansions with ten years' perseverance and devoted himself to the revision. After his death, he left the first eighty manuscripts of A Dream of Red Mansions. A Dream of Red Mansions is a great realistic work in Chinese classical novels, with rich content, tortuous plot, profound ideological understanding and exquisite artistic techniques. The last 40 of the existing 120 chapters in A Dream of Red Mansions are generally considered as Gao E's sequel (about1738-about 18 15). Cao Xueqin's great-grandfather Cao was a weaver in Jiangning. Great-grandmother Sun Shi was the nanny of Emperor Kangxi Michelle Ye. Grandfather Cao Yin worked as a squad leader and bodyguard in Michelle Ye, and later as a weaver in Jiangning, who also served as an inspector of salt affairs in two Huai provinces, winning the favor of Michelle Ye. Michelle Ye visited the south of the Yangtze River six times, was taken back four times, and lived in Cao's home. After Cao Yin's death, his sons Cao Qing and Cao Fuxian succeeded him as Jiangning Weaving. Their three generations and four grandchildren have held this position for 60 years. Cao Xueqin grew up in the "prosperous" life of this "romantic place of Qinhuai" since childhood. In the early years of Yongzheng, the Cao family suffered a series of blows because of the political struggle within the feudal ruling class. Cao Fu was dismissed on charges of "misconduct", "harassing the Post" and "deficit", and his property was confiscated. Cao Fu was imprisoned and punished, and the "cangue" lasted for more than a year. At this time, Cao Xueqin's family moved back to Beijing. Since then, the Cao family has been devastated and declining. After a major turning point in his life, Cao Xueqin felt that the world was cold and had a clearer and deeper understanding of feudal society. He despised powerful people, stayed away from officialdom and lived a poor and hard life. In his later years, Cao Xueqin moved to the western suburbs of Beijing. Life is even poorer, "covered in wormwood" and "porridge for the whole family". He devoted himself to the writing and revision of A Dream of Red Mansions.
