When applying to join the party in college, you are assigned a class quota every year, that is, 2 to 3 students, with a maximum of 4 to 5 students. In other words, within a year, a class can only absorb two or three activists to join the party. The quota for joining the party is relative to the total number of college students in the class. Often only a dozen. This data means that during the four years of college, there are often more than a dozen activists in the class who can join the party. Considering that it takes a long time for a university to apply for membership in the Party, and the procedures are very strict, if the freshmen and sophomores can't become party activists, it means that it is unlikely that they will become official party member during their university years.
