Because these institutions have succeeded in self-examination, they have cooperated with a large number of schools and accumulated many years of enrollment experience and a strong publicity team. On this basis, natural universities choose to cooperate with them, which is much more profitable than setting up their own enrollment team. In principle, such institutions should not charge registration fees after collecting agency fees from colleges and universities. However, some unscrupulous institutions charge student service fees under the banner of "paying money". It is not known whether there will be other excuses to charge other fees here on the grounds of tuition and miscellaneous fees of an institution in the later period.
