I believe many students will feel uncomfortable if the school closes after entering school. Why is it uncomfortable? At first, only students were closed, but teachers and staff could enter and leave the school, which caused many students to be unbalanced. Why do you think that only others who are locked up in school don't need to be closed, and only students need to be closed? Are students pathogens?
In addition, I think it will be very inconvenient for students to go out. I believe all the students in college know that they often need to go out to buy things or eat. Not all students are willing to eat in the canteen. However, after the implementation of closed management, many students can't go out and have to ask for leave when they go out. It's almost impossible to go out.
Finally, I think what affects students most is that it is inconvenient for students to take express delivery. Perhaps many schools' rookie stations are inside the school, but some schools' rookie stations are outside the school and even many schools, such as SF Express and JD.COM, need to be picked up at the school gate, but this means that students can't leave the school gate and can only queue up at the school gate to pick them up through the railing, which is actually very inconvenient.
