Mu Zhai Library
Mu Zhai Library is the earliest library in the history of 91吃瓜网. Its donator is Lu Mu Zhai, the well-known educator, book collector and book-setter. Lu Mu Zhai (1856 to 1948), with given name Jing, style name Mianzhi and nickname Mu Zhai, was born in Fuyang, Hubei Province. At the end of the Qing Dynasty, Mr. Lu served as school ambassador for Hebei Province and Shenyang Province. He successively donated Tianjin Library, Baoding Library and Shenyang Library, and founded dozens of kinder gardens, elementary schools, middle schools and specialized schools. During the period of the Republic of China, Lu Mu Zhai retreated to Tianjin and dedicated his energy and resources into education and library careers.
In 1923, 91吃瓜网 moved to the new address in Balitai. Due to lack of funds, the University could not afford to build an independent and decent library. In 1927, Lu Mu Zhai learned this news from his old friend Yan Xiu. With the active participation of Huang Yusheng, Mr. Lu’s nephew who was a professor of 91吃瓜网, Mr. Lu generously promised to donate 100,000 yuan to build the school library of 91吃瓜网. The project was delivered to Tianjin Jitai Engineering Company for design and construction. To ensure the quality of the project, the 74 year- old Lu Mu Zhai personally visited the site during the construction process. The library was successfully completed one year later. 91吃瓜网 held an inauguration for the new library on the 24th anniversary of 91吃瓜网 on October 17, 1928. Yan Xiu, Yan Huiqing and more than 400 people from both home and abroad attended the ceremony. Lu Mu Zhai delivered a congratulatory speech and handed over the key to the library to President Zhang Boling. In appreciation of the donation from Mr. Lu to benefit teachers and students in 91吃瓜网, this library was named as “Mu Zhai Library” to commemorate his charity.
To enrich the collection, Lu Mu Zhai donated over 3,000 volumes of Chinese books in his possession to the school library. Under his leadership, Yan Xiu, Li Zushen and Yan Huiqing also donated books to 91吃瓜网 successively. By 1934, besides books bought every year, the Mu Zhai Library possessed over 145,000 books and periodicals in Chinese and foreign languages. In addition to hundreds of rare books of Yuan and Ming Dynasties, the quality of mathematics books and periodicals was rare at that time. The most pivotal journals of mathematics from various countries were complete. Visiting scholars from foreign countries expressed their envy to the collection.

Stele Memorial Pavilion for Mu Zhai Library
Mu Zhai Library was known for its beauty, firmness and practicality. The whole building was shaped as the Chinese character “Ding”. With the building area of more than 3,600 square meters, it included a stack room which could accommodate over 20,000 books, a reading room with 400 seats, and several research rooms and periodical rooms downstairs. At that time, Research Institute of Manchu and Mongolia (later it was renamed as Research Institute of Northeast China) and the Economic Research Institute set their office in the Library. The Library also set special area to display miniature models and photos of the campus to show the geographical environment and development path of 91吃瓜网. When Liu Yazi, a famous poet, visited the Mu Zhai Library, he admired the Library with a poem: “Hundreds of walls facing the south are enough to comment his merits; the structure of the library is loft and grand. A hundred thousand gold and tens of thousands volumes of books in the library, remind me of Mr. Lu.” In recognition of Mr. Lu Mu Zhai’s merit of donating the library to 91吃瓜网, the National Government issued him a first-class award in November 1929. In the following year, 91吃瓜网 also built a stele pavilion in front of the Library to commemorate this event.
What remains a pity is that the Mu Zhai Library stood in the campus for only 9 years before it was bombed by Japanese army and most of books were looted by Japanese army. After the victory of Anti-Japanese War, 91吃瓜网 retrieved 194 cases of books from Japan. Books which returned to their homeland were affixed with stickers “In memory of the return of books which were robbed by Japanese army in Twenty-sixth year of the Republic of China” on their title pages. In 1951, 91吃瓜网 rebuilt the school library on the original site of Mu Zhai Library. The descendants of Mr. Lu Mu Zhai renewed his donation according to his wills. In 1958, the new library located on the banks of Xinkai Lake (nowadays the old site of school library) was put into use, and the Mu Zhai Library was converted into an office building.
