Zhu Xizu began to collect books in Japan when he was a student. After teaching in Beijing, he even ran from north to south, catching things from east to west, saving money for rare books. His Bibing Collection enjoys a high reputation in academic circles. 19 1 1 in the book collection chronicle poem Zhu Xizu, Lun Zheru said: "Who doesn't praise Zhu Hu in the bookstore (because Zhu Xizu had a beard at that time), just anecdotes and bamboo slips constitute a defeat. Don't be stingy with a thousand dollars and a famous horse, ask the scholar for a book. " The poem wrote: "Pei was the first ancestor to buy books, and he was also the most eager to buy books." He paid the money without hesitation. At the end of the year, he took a huge Golden Week bookstore, which was left and right, so he paid for it. I also tried to pay the value to the bookstore, and once I got the compensation for the book. So you have got many excellent books, from the proud library to the private one, which are not comparable to you. " In this way, it has accumulated for decades, and Bi Ting's collection has reached 250,000 copies, with more than one million copies in its heyday, among which there are many rare books, such as Shan Shu, Ya Jiang Xing Bu Zhi, Zhu in Song Dynasty and Ming Dynasty. All these are unique to China. Among them, the Song version of Notes on Water Mirrors was once praised by Wang Guowei as the first of Notes on Water Mirrors. Mr. Zhang Taiyan and Mr. Wang Guowei wrote the postscript for this book successively, and Mr. Xu Shoushang and Mr. Wang Donger signed it. Later, Mr Hu Shizhi also wrote a textual research article for this purpose. It is for this reason that Zhu Xizu named his library "Biting Pavilion" and asked Zhang Taiyan to write a plaque. Bi Ting's collection is mainly based on historical materials and Nanming local chronicles, with historical books, anthologies, recitations and even ancient books and manuscripts as the main collection objects.

Zhu Xizu likes to collect ancient books. He can find precious engravings of Ming and Qing Dynasties, historical records, local chronicles and manuscripts of unofficial history and Nanming in Song Dynasty. At first, the collection of books was to collect information for studying the history of the late Ming Dynasty, and the information collected in unofficial history was very rich. He collected most of unofficial history collected by Miao, especially the historical materials of the Ming Dynasty, and there are many other manuscripts and manuscripts. Li Daoyuan's Notes on Water Mirrors in the Ming Dynasty had a very rare edition, so he ordered his collection to be Li Ting, and Zhang Taiyan wrote Li Ting for him. According to the statistics in Biting Books Bibliography, there are about 4,000 species, which are divided into five parts: the classics, history, books, collections and local chronicles of Haiyan. The history department has the largest collection of books, about 2000 kinds, many of which have titles and suffixes, so it is called "reading bibliophile". After liberation, his son Zhu Wedge sold some books about the history of Nanming and some prints of Song Dynasty to Beijing Library, while most of the rest were donated to Nanjing Library. The library is printed with "Li Ting", "Zhu Xizu Seal" and "I read it first".

He is the author of five volumes of Textual Research on Jizhong Book and eight volumes of Chronology of Warring States Period. These two books are typical examples of studying history. He collects ancient books, especially local chronicles, and a large number of local chronicles of Guangdong and Guangxi, especially historical materials of Nanming. Zhu Xizu used epigraphy as an auxiliary material for historical research, and made textual research on the chronology of bamboo slips. He experienced the tombs of the Southern Dynasties in Nanjing and was more interested in collecting ancient cultural relics, including Yi Wei, coins of the Five Dynasties, Buddhist scriptures, iron coins of the Song Dynasty, silver coins of the Yuan, Ming and Qing Dynasties unearthed in Sichuan and Hubei, and copper coins such as Koryo and Annan.
