Cao Yin (1658- 17 12) is ziqing, whose name is Li Xuan and Ding Dong. His predecessor was the Han nationality. From his grandfather, he was the coat (slave) of the Manchu nobility, and the Han army in Manzhouli was the white flag. When my father Cao was weaving in Jiangning, he tried to plant some trees in the department. They were green and lovely. Because the pavilion is called "Dongting". Mother Sun Shi was Kangxi's wet nurse, so Cao Yin had the opportunity to enter the palace as Kangxi's class capital at an early age, and later imitated his father to do Jiangning weaving.
Cao Yin is good at reading and collecting books. During his weaving in Jiangning, he made friends with Han literati, including many famous bibliophiles, such as Xu, Zhu Yizun, Song Muzhong and Wang Shizhen. Cao Yin often borrowed books and copied books from them, especially the rare books in Zhu Yizun, almost all of which were copied by Cao Yin. Li Wenzao's Book of Liulichang: "Dong Ting has been weaving politics for more than ten years, and he has made friends with Zhu and exposed the book of the pavilion. Dong Ting has a copy of the money. As far as I can see, books such as Description of Stone Carvings, Chronicle of Song Dynasty, Tale of Taiping Universe, Mystery of Spring and Autumn Period, Chronicle of Later Han Dynasty and Chronicle of Chongzhen are all banknotes. " Wei Heshan's Selected Poems of Mao Zedong and Collected Works of Building Attacking Shame are both Song manuscripts. Of course, in exchange for the needed items, Cao Yin also lent his library to Zhu Yizun for copying. Ye's Chronicle Poem of Collection of Books describes: "The trees are full of herbs, and the next one is the Neem Flower Pavilion." Director Jin Fengge visited Japan, and Song Xie scattered money all over Zhu Xi. Cao and Zhu took books as friends and became close friends, and the book forest became a much-told story.
After years of hard work, Cao Yin finally hid more and more ancient books, sat in the book city and swam in the pavilion, very complacent. There is a book uncovering in Volume 2 of Ten Summer Poems by Dong Chao and Zhiyuan: "It took fifteen years to find it busy to uncover books. Regret and sweat "Sometimes there is a breeze to send ancient incense. "In the forty-fourth year of Kangxi (1705), Cao Yin compiled the Dongzi Pavilion Bibliography in four volumes, divided into 3 16 categories, and recorded 3227 kinds of books. There is a "Three Seas Series".
After The Complete Poem of Tang Dynasty was written, Cao Yin felt the importance of phonology for poetry creation, and compiled five previous phonological books: Jade Piece of Yi Hui in Datang, Rebuilding Guang Yun in the Great Song Dynasty, Gathering Rhyme, Leipian and Notes to the Book of Rites, and carved them into Five Kinds of Dongting. Every book is printed with a collection of Dongting books.
Shortly after Cao Yin's death, the Cao family was confiscated for political and economic reasons, and the collection of books in Dongting was also dispersed. Li Wenzao's Liulichang Bookstore said: "On May 23rd ... I bought dozens of books from the inner city, each of which was printed with" Cao Yin in Dongting "and" The Long-lasting Book Seal of Violet in Changbai Fu Cha ". Changling means Fucha Changling, his name is Fucha, and his name is Zi Qi, the nephew of Cao Yin. Later, Sun Xingyan, Ding Richang, etc. They all collected the old things in the pavilion.
