Recently, people's lives have been greatly affected by repeated and serious epidemics, among which the influence of schools is relatively great. As an area with a very concentrated number of students, schools are prone to spread epidemics, and some schools have recently discovered epidemics on campus, so the teaching work of schools has to stop offline teaching.
But this is not to stop classes, because the teaching task is still there, so students usually switch to online classes and let them go to the dormitory or go home for online classes on holidays, so as to minimize the large-scale gathering in the classroom and thus reduce the risk of epidemic spread. Therefore, the suspension of offline teaching is also for online classes, or for studying with peace of mind and completing learning tasks.
