 Many university students walked out of classrooms at Tsinghua and other institutions, and some went on to join the Red Guards, resulting in the complete shutdown of the university as faculty were persecuted or otherwise unable to teach.It was not until 1978, after the Cultural Revolution ended, that the university began to take in students and re-emerge as a force in Chinese politics and society.In the 1980s, Tsinghua evolved beyond the polytechnic model and incorporated a multidisciplinary system emphasizing collaboration between distinct schools within the broader university environment.
