《虚白斋尺牍》抄件是近年来在苏州织造李煦祖籍山东昌邑发现的李煦遗著,是新中国成立以来发现的最大一宗与李煦及其家族有直接关系的新资料。该抄件涉及内容广泛,对康熙朝政治经济史研究、李煦及其家族研究、曹寅及其家族研究、《红楼梦》研究均具有重要价值。 The copy of “Imaginary Zhai Ruyi” is the remains of Li Xu discovered in Suzhou in recent years by weaving Li Xu's ancestral home in Changyi, Shandong Province. It is the largest piece of material found directly related to Li Xu and his family since the founding of new China. The copy covers a wide range of contents, and is of great value to the study of the political and economic history in Kangxi, the study of Li Xu and his clan, Cao Yin and his clan, and the study of “Dream of Red Mansions”.
