Shanghai Jiao Tong University's Minhang CampusProfessors and other academics at Shanghai Jiao Tong University have collaborated to deliver meals to students under quarantine, as the university's Minhang Campus has been put under closed-loop management.With more than 30,000 students quarantined in their dorms at 800 Dongchuan Road, it's a challenge to deliver meals to all of them every day.The staff voluntarily entered the loop to serve their students. They now live in offices, meeting rooms, libraries and labs on campus, where they also teach online classes.
