Although the epidemic situation in China has been effectively controlled, we can't avoid some potential dangers, so we should always be careful to prevent the enthusiasm of the virus from spreading. Students who return to school to take CET-4 and CET-6 after graduation should be isolated for seven days at their own expense. Is this reasonable? In my opinion, it makes sense. Let's analyze it in detail.

Although the domestic environment in China is relatively safe now, the epidemic situation in some foreign countries is still rising, so our general environment is still unsafe, and it is a relatively safe environment in schools, because teachers, students and staff in schools are all allowed to enter schools after nucleic acid testing, and there are still students in schools now. They are all isolated, not allowed to leave school, and only contact with teachers and classmates in the school. However, if they go back to school to take CET-4 and CET-6 after graduation, and don't do nucleic acid testing, or the people who come into contact outside the school are complicated, they are not sure whether these people carry the virus or not, and they need to be isolated to ensure the safety of students.

And CET-4 and CET-6 are all voluntary. Therefore, it is reasonable to isolate the graduates at their own expense if they go back to school to take the CET-4 and CET-6 exams first, because if they are not isolated, it is easy to bring the virus to school, and the school is a crowded place. Once an infection occurs, it will be a cluster infection, and the impact will be very great. Therefore, if you want to be in line with this business, you would rather kill one thousand by mistake than let one go.

Therefore, it is very normal and reasonable for students to be isolated for seven days at their own expense, because this is caused by this big environment. Although the domestic environment is relatively safe now, this matter cannot be taken lightly.
