In recent years, with a continuous increase in the number of college students in China, the limits to the campus land use and the needs for improved functions have become more and more paradoxical, especially for traditional campuses. The problems caused by this issue are acute. The research and practice of campus renewal for time-honoured campuses, such as Peking University (PKU), are of great significance for both its renewal and reconstruction. In this report, the creation of a pleasant learning environment in a traditional Chinese campus was theoretically and practically explored through the two real projects of the Centennial Memorial Hall and the Humanities Buildings in Yan Yuan of Peking University. Multiple possibilities of organic upgrades and cultural inheritance of the campus were sought by offering open spaces, and indoor and outdoor spaces, to meet the functional requirements, meanwhile, creating a growth-based campus environment and continuing cultural inheritance in the hope of inspiring the creation of contemporary campus environment based on tradition.
