Generally not, you can rest assured of this.

If you cross the shift line of a university and are transferred, just fill in the transfer. Then even if you can't fill in the scores of your major, the school will transfer you to other majors.

At the admission site, it is generally stipulated that candidates who obey the adjustment will not withdraw their files in principle. When entering the venue, there will also be staff on site who will be responsible for supervision and coordination. According to the regulations, parallel volunteer batch will be implemented. If the candidate chooses a major subject to adjustment, in principle, he is not allowed to quit except for normal reasons (professional disobedience and physical restrictions).

Therefore, we must pay attention to the choice to obey the adjustment.
