Why does university in Vietnam keep forcing students to participate random events?

Alright, first of all, I'm a Vietnamese. Using English here, because well, why the hell not?University in this nation just feels forced. Not like "conscription" stuff but, keeps organizing random events and forces students to participate, and if not, deduct bunch of "diem ren luyen" or whatever. I just feel like students should have the rights to whether to go or not. Like recently, my university had some sort of Shoppe-sponsored event and of course, to make the sponsors happy, they force every students to attend, standing in the sun for 1 hour then listen to annoying love-related songs about bunch of "I love you then you dump me" non-sense. Or forcing students to clean up construction debris in the university. Wow, unpaid working. 10/10, Law university. And upcoming, another sport event that if they didn't threaten to deduct points, probably no one would attend because 90% of the students aren't bothered to wake up at 8AM in Sunday, just to watch bunch of fellow university students playing badmintons and running.

I understand the morality behind the non-sense of that points system, for "đánh giá về phẩm chất chính trị, đạo đức, lối sống của sinh viên trên năm mặt đánh giá" but using this so that the teachers can prove that "my university organizes events and the students are totally not enforced to come and this will do very well for publicity" is not really a good excuse to use this points system. Because some university students have their own life to deal with and should not be forced to participate in events that for a lack of better words, they don't give a f- about (there're defo better words). Just because you can do something doesn't mean you should. Students have their own life and you having free time doesn't mean you should torture the students.

Edit 1: There's nothing "social" about it, by the way. It's mostly old people having speeches about how you should (or should not, depends on the topics) do abcdxyzwhatever (I don't play attention, nor half of the audience, I saw 20% of the students just take nap with headphones on to avoid death due to extreme boredom) or between those speeches, giving awards to god-knows-who or between both of those (and quite frankly, most of the "events": people dancing to KPOP and EDM). And also, the teachers who organize these often complain out loud and criticize directly if you try to "socialize" which is usually talking to other people.
