Large-scale enrollment is generally carried out between similar institutions. In the past, you had to apply for a specific major in the college entrance examination, but you can't change it when you enter the university. Large-scale enrollment is to "package" several similar majors into one category. Candidates originally had only one major choice, but now there are many majors to choose again after entering the university. Large-scale enrollment is very beneficial to candidates. According to the fact that candidates have entered the university for one year, they have a deeper understanding of their major and a clearer understanding of whether their interests and specialties are suitable for this major.
