Solicitation of volunteers means that in the process of enrollment, the number of people who originally applied for this volunteer is not enough. Only by collecting volunteers again can we enroll the number of students who plan to enroll. After the start of school, the enrolled students gave up the school, and the number of students in the school could not reach the enrollment plan. If a student is admitted again, it's called make-up. In fact, during the period of voluntary admission, the concepts of re-recording volunteers and soliciting volunteers are basically the same, but the re-recording at the end of freshman admission is generally no longer used.
