Main Library North Section, Academic library in Qinghuayuan Subdistrict, China.

The North Section, also called the Li Wenzheng Building, was completed in 2016 as the fourth phase of the Tsinghua University Library, at the campus centre. It was funded by the Indonesian Chinese businessman Li Wenzheng and designed by Guan Zhaoye, an academician of the Chinese Academy of Engineering. The building holds over 600,000 volumes and 800 reading seats, with five floors above ground and two below; a sunken courtyard at basement level brings daylight in, and a sunken plaza lies outside.

The building opened in 2016 as part of the ongoing expansion of the university's library system, which traces its origins back many decades. This addition followed the gradual growth of collections and shifting needs of the institution across generations.

The library serves as a gathering place where students walk between shelves, discuss ideas at tables, and study together across different disciplines. The space fosters daily interaction and creates a sense of shared intellectual community among those who spend time here.

Visitors should know that different areas are available for working, from quiet corners to spaces for discussions. It is best to arrive early in the day when it is less crowded and easier to find a good study spot.

The North Section, also called the Li Wenzheng Building, was funded by the Indonesian-Chinese businessman Li Wenzheng and designed by Guan Zhaoye, an academician of the Chinese Academy of Engineering. Because the library's first and second phases are listed as National Key Cultural Relics Protection Units, the new building was kept no taller and no larger than the older library. Its footprint covers 10,600 square metres, with 15,938 square metres of total floor area on five above-ground and two basement levels.
