National Library of China
Several early manuscripts are still extant. At the present, the "Jiaxu manuscript" (dating to 1754) is held in the Shanghai Museum, the "Jimao manuscript" (1759) is held in the National Library of China, and the "Gengchen manuscript" (1760) is held in the library of Peking University. Beijing Normal University and the Institute of Oriental Studies of the Russian Academy of Sciences both also held manuscripts of the novel that predate the first printed edition of 1791.
