What if students change seats and don't cooperate?

Student seats are a difficult problem. There are many options available in practice, but each has its own advantages and disadvantages, and it is impossible to satisfy all students' wishes. But fairness and openness are the first principle and cannot be linked with students' grades. However, poor students should be treated in secret, and it is best to choose their seats at random. For students who are finally dissatisfied (all students can), they only have one chance to choose the place they want to go. As long as your seat and target seat meet four people at the same time, you can adjust freely, and then ask all the seats around four people. If half of the anonymous votes are against free adjustment, they will be resumed, and then the anonymous votes will be destroyed so as not to hurt the students' mood. For adjustment, I suggest this. Two people sit at the same table 1. Divide men and women first, 16 for men, 14 for women, make 1- 16 for tickets, and boys draw. Same number at the same table, so do girls. 2. Mark the seat pair with the coordinates before and after the seat. When drawing lots, let the girls draw first, and then the boys draw again. When drawing lots, the teacher should make it clear that the probability of success is the same. Finally, if B who is too tall sits in the front, give him a chance to choose a seat in the back (same sex). If the original seat of A and its original seat are agreed by four people, let the two seats of A and B be adjusted freely. Any one disagrees, and no adjustment is allowed. 4. If the remaining student C is not satisfied with the present situation, refer to 3 to let him choose a seat for D (. In addition, in this case, let the students around C/D say whether they agree or disagree after the adjustment. If more than half of them object, it depends on random and fair voting. After a round of adjustment, I believe everyone will adapt. Of course, before implementation, teachers should explain the whole process of the plan.
