Through a textual analysis of the 38 guiding policies for Chinese undergraduate teaching reforms in the past 70 years, the researcher has found out that the reforms have gone through stages of foundation, reconstruction, education system reform, teaching content reform, and improving teaching quality. Prominent progress has been achieved in the undergraduate teaching, curricular construction and integration, and teaching quality control. In the future, Chinese undergraduate teaching reforms will be committed to learner-centered teaching, digital integration of curriculum and teaching methodologies, teaching quality evaluation and monitoring based on big data technology, and innovation-based new achievements in the new era.
