In order to ensure the smooth development of undergraduate enrollment publicity work during the prevention and control of COVID-19, Tongji SEM organizes 2020 Undergraduate Adminissions Campaign online. It is expected to improve the quality of undergraduate students, and actively explore new ways and methods of enrollment publicity. SEM plays the advantages of Internet, launching the online social platform to carry out enrollment publicity work. As the first special session of the event, the online information session on Zoom was arranged to share information and interact with the students and parents across the country on March 27.
