Since the outbreak of the epidemic in the United States, studying abroad that cost millions of tuition fees has become a "correspondence" class in TVU. Since the first half of last year, American university courses are basically conducted through online courses. This is not like children's enlightenment education, University specialisation requires a high level of classroom instruction.

The teaching quality of online courses is definitely much worse than that of classrooms, especially when it comes to the study of physics, chemistry and other majors, as well as the review of various documents. Therefore, the president of Boston University said in his reply to the petition letter full of concerns from international students that the school could not. Each course is taught online, so offline courses are required.

Coupled with the absence of students, the university's dormitories, canteens, etc. have also lost a large amount of daily income. Over time, universities around the world have become more and more unable to make ends meet. Many universities charge additional fees of several thousand dollars to maintain a balance of payments. , so even if the danger of the epidemic still exists, universities have to start mandatory resumption of classes.
