In a university in Zibo, a self-made conveyor belt was used by the stall owner who sold snacks outside the school to deliver the goods from a small stall to the students of the school. The stall owner was also doing business, so there was no risk. Because people who do business near the school are also people near the school, an area is safer and naturally safer.

college students, especially in the last two years, should have a very obvious experience that the school is becoming more and more closed. Originally, the university was an open world, but it was normal to go out to buy some delicious food or go shopping and watch movies, but it was affected by the epidemic, but they couldn't go out. Moreover, students will find a very strange phenomenon, that is, only students are really closed, and teachers and school staff can freely enter and leave the school gate. In fact, such a blockade didn't play much role in prevention and control, so in the end the school turned a blind eye.

Because schools should be very aware of what students do in school, such as ordering take-out food in school, picking it up through fences, picking it up through fences, or taking a long pole and a conveyor belt to deliver some off-campus snacks through these special means, from the perspective of strict prevention and control, these behaviors should not happen. However, the school also knows that it is of little use to strictly control students from contact with the outside world when faculty members are free to enter and leave, so it is better to let go a little. Because if the students are strictly controlled, the students will have a big opinion in the end, and the final result will be that everyone will be closed in the school, otherwise there will be public grievances among the students, and this matter will not end.

Water can carry a boat, but it can also overturn it. Although it is said to be the ruling speech of ancient rulers, it is also a general school to some extent in the management of schools now. It can manage students, but it can't cause public anger. There are 91 students out of 1,111 who feel that there is something wrong with the school and all of them report it. If the school doesn't solve it, it won't end so easily. Schools can't stand on the opposite side of students, but only adopt guidance and management.
