During this period, Wei offered eight courses, including an introduction to phonology, dialect studies, phonological studies, folk literary speeches, phonological history and ancient phonology. In 1930s, there were three summaries in Chinese Department of Peking University, namely, Hu Shi's Outline of China Literature History, Shen Jianshi's Outline of Philology and Wei's Outline of Phonology.
Wei is one of the more successful people in phonological research after Wang Guowei. He published a series of papers on the study of ancient rhyme. For example, according to the relationship between Qieyun and the rhyme books of the Six Dynasties, this paper studies several rhyme books before Qieyan in Lv Fayan, and explains the evolution of the rhyme book system in Tang and Song Dynasties according to the differences between them, which supplements and develops the previous theories.
In phonological research, Wei attached great importance to textual research and advocated the spirit of "simple learning". He used ancient rhymes, Chinese initials and other materials to research ancient sounds, emphasizing the accuracy of materials and the rigor of methods. After the founding of New China, the textual research on the origin of the second rhyme in Qieyun and the explanation of the inconsistency of the four rhymes in Qieyun all reflected his academic characteristics. After the May 4th Movement, Wei took an active part in the movement of new culture and new ideas, and published many essays under the pseudonym "Xing" in publications such as Mangyuan and Yusi led by Lu Xun. After liberation, he was a member of the Chinese Writers Association.
