Humanities and social sciences originated from the rise of the modern nation-state, and the interpretation and criticism of modernity have always constituted its classical tradition, but at the same time, the pervasive penetration of modernity has also exposed the development of humanities and social sciences to the danger of alienation. As an overcoming and surpassing of the modernity of modern social sciences, new liberal arts is a new form of liberal arts knowledge production and reproduction in the post-industrial era based on highly integrated, informatized and digitized knowledge. It takes cross-cutting frontier, strategic needs, modern technology and regional advantages as its driving force, and the construction of majors and curriculum systems, the construction of interdisciplinary faculty, the establishment of teaching and research evaluation standards and the formation of operation modes as its four core elements. In the specific construction practice, exploring domestic and foreign interdisciplinary joint degree training, establishing a modern academy system based on multidisciplinary clusters, promoting the construction of "new liberal arts laboratories" and practicing "traditional liberal arts +" can become four models for universities to explore the construction of new liberal arts.
