There are two main theories about Cao Xueqin's ancestral home, namely "Feng Run Theory" in Hebei and "Liaoyang Theory" in Liaoning. The theory of "abundance" was put forward by Li Xuanbo. 193 1 In May, he published "A New Examination of Cao Xueqin's Family" in the Palace Monthly, pointing out: "Cao Yin is really a rich man." 1947 65438+On February 23rd, Zong Ping published the article "The Birthplace of Cao Xueqin" in Qingdao Yanmin Daily, and also thought: "Xue Qin was a rich man in his last life."

Later, he inherited and developed the above statement, and in the third chapter of A Dream of Red Mansions, he clearly stated that Cao Xueqin was from the county. One of his arguments is that his grandfather called Cao @ ⑦ and Cao @ ⑨ brothers second and fourth brothers many times in his poems, and mentioned their "flesh and blood" relationship, saying that they were "by no means relatives with the same surname". His second argument is that "Cao Xueqin's distant ancestor went through Feng Run after Yongle in the Ming Dynasty". The seventh chapter "Chronology of Historical Events" says that "according to Cao Shi's genealogy, his ancestor Yongle moved from Jiangxi at the beginning, and one of them lived in Tieling, so Cao (also known as Cao Xiyuan, the ancestor of Xueqin) may be from Tieling Wei or nearby areas." According to the genealogy of the rich Cao, he wrote "Cao Duanming, whose character is Ming, followed by Song". Duan Ming's younger brother Duan Guang was born in Tieling Wei. Some people suspect that in this year's Tieling campaign, it was not Cao himself who was captured as a slave, but they should have their own people. "Zhou Yi Cao Xueqin is the descendant of Cao Duanguang, the younger brother of Cao Duanming, the ancestor of a wealthy businessman, to prove that he is a wealthy businessman.

1980, Feng Qiyong's A New Examination of Cao Xueqin's Family History was published by Shanghai Ancient Books Publishing House. According to the genealogy of Cao Shi in Liaodong rebuilt by Wuqingtang, Mr. Feng concluded that Cao Xueqin's ancestor in Liaoning was not related to Cao Duanguang who entered Liaoning with wealth. 1996 A Dream of Red Mansions series 1 published Liu Shide's Re-evaluation of Abundance. This paper criticizes the fallacy of "Feng Run Lun" from seven aspects, and sorts out 17 important materials, such as: "Zhejiang Tongzhi Volume 122:' Cao is from Liaoyang and Fengtian. ""Records of Datong in Qianlong "(Volume 2 1):' Cao Yanzhen was born in Liaodong. ""Jiaqing's Shanxi Tongzhi Volume 82:' Cao, a native of Liaoyang, a native of Fengtian. " ""Kangxi's "Shangyuan County Records" Volume 16 Cao Xichuan:' Born in Xiangping. "Xiangping is the county name of Qin, which is located in Liaoyang City today." The title of Cao Yin's poetry anthology. Poems of Cao Yin was published in the fifty-second year of Kangxi (17 13). Among them, Poems on the Neem Pavilion was written by Cao Yin, with a total of 8 volumes, and each volume was prefaced by Qing Zi, Cao Yin and Qianshan. Qianshan is another name for Liaoyang. "Cao, Cao and Cao Xueqin's great-grandfather, great-grandfather and grandfather respectively. Liu Shide's thesis shows that the Qing people generally recognized Cao Yinjia as a native of Liaoyang in Fengtian, and what is more authoritative is that Cao Yin called himself "Qian Caoshan and Yin Ziqing" in his poetry collection and considered himself a native of Liaoyang. This is the ancestral home of Cao Xueqin.

1In July, 1997, Liaohai Publishing House published Cao Xueqin's ancestral home in Liaoyang, edited by Feng Qiyong and Yang Lixian, and included 40 papers, which proved that Qin Xue's ancestral home in Liaoyang was reliable in many ways. 1998 1 China encyclopedia publishing house published Liu Shide's "Discrimination of Cao Xueqin's ancestral home". The book has 22 chapters and more than 500,000 words. After the first chapter "the importance and particularity of Cao Xueqin's ancestral home", ten special chapters are used to prove that Cao Xueqin's ancestral home is Liaoyang from ten aspects.
