After reading the text, it is clear that the questioner is torn between defending his or her rights and interests and maintaining a fair position with others. He or she is afraid of being called "selfish" for defending his or her rights and interests, which arouses the "outrage" of those around him or her.
"Every time there is a big clean-up, there will be a student in charge on Monday. Today, I had to clean the classroom quickly, so I went to buy some flour to eat back in the dormitory. When I arrived, they were still cleaning. The person in charge of hygiene in the dormitory saw me come back so quickly and said, 'You can take out the trash now.'
The person in charge of dormitory hygiene clearly didn't realize you had already cleaned the classroom. After you finished your "share of the work," you returned and they thought you weren't working, so they assigned you to take out the trash. This was a way to balance the situation so everyone else in the dormitory would feel "fair."
"I was originally supposed to take out the trash in the dormitory today, so I didn't say anything because I had to wait until they were done cleaning before I took out the trash. I ate some powder first, reading a novel while I ate. At this time, the person in charge of cleaning in the dormitory was dissatisfied with my laid-back attitude and insisted on assigning me other cleaning duties. I refused, and she gave a loud huff,"
Your silence is seen as tacit consent. The person in charge of arranging the dormitory's hygiene may think you are silently protesting, refusing, or even provoking.
You didn't act according to her demands. You were leisurely eating powder and reading novels. She may feel her authority has been challenged. She may also be afraid of complaints from the other people in the dormitory. Your behavior forms a sharp contrast with that of others.
The person in charge of arranging the cleaning schedule "insists on arranging other cleaning tasks for you." She thinks that if you are unwilling to take out the trash, you are willing to do other things. When you refuse again, she may realize that "you just don't want to do it," or that you "don't want to listen to her arrangements." She announces "the end" by "loudly making a sound" to express her own helplessness and dissatisfaction and to "account for it" to the other people in the dormitory.
"It's very annoying, and I'm beginning to wonder if I'm not being a good friend." The questioner feels angry, but she also feels the pressure of the person who arranged the cleaning. Perhaps she still represents the "more authoritative and moral" side? This makes the questioner a little worried and afraid of causing "public anger."
"If I agree to this, she'll definitely ask me to do other things next time, and if this continues, I'll have to clean the classroom and dormitory every time I do a big clean. I'm not going to do that." The questioner inadvertently believes that "if I agree to this, it's the same as giving her permission to keep asking me to do things in the future," which is a "very big power to give."
I can't do it myself, and no one else can either. This way, the questioner can feel "more at ease" and give others a "reasonable explanation." If they criticize you, they'll just have to deal with it.
"I am someone who is particularly affected by interpersonal relationships. If someone in the dormitory has a conflict with me, I will be very depressed, pessimistic, and even unable to study, but I don't want to give in." This is a characteristic of adolescence. On the one hand, you want to integrate into the "larger outside world," but on the other hand, you are worried that you will lose yourself because of this integration. You need to do something to protect your rights and boundaries. Your three values and self-identity are shaped in the midst of these "collisions"...
You should be able to express what you want to say so that those around you know what you mean. For example, when the person in charge of cleaning tells you to take out the trash, you can respond to her: "I know, I'll take out the trash after you're done cleaning. I'm going to eat something and take a break, I'm tired after cleaning the classroom."
This way, you show that you are not lazy and respect the person who arranged the cleaning. It also eliminates any misunderstandings or misinterpretations that others in the dormitory may have.
I am certain that my reply will help you. Best wishes!

I understand how you feel; it's tough being in a situation where you're trying to relax after doing your part, only to face additional demands. I think it's important to set boundaries and communicate them clearly. You could explain that you've already finished the classroom cleaning and need some downtime.
It sounds like you're feeling quite pressured and unsure of yourself. Maybe it would help to have a calm conversation with the person in charge about dividing tasks fairly. It's not selfish to want a fair distribution of work. Everyone needs a break sometimes, and it's okay to say no when you've done your share.
The way she treated you seems unfair, especially since you had already completed your duties. It might be worth talking to her or even the dorm supervisor about establishing a clear schedule for chores. That way, everyone knows what's expected and there's less room for conflict.
You're not alone in this; many people struggle with similar situations. It's important to stand up for yourself without escalating the tension. Perhaps you can propose a meeting with all the dorm mates to discuss how to handle cleanup days more efficiently and respectfully.
Feeling conflicted is natural, but don't let others make you doubt your efforts. If you're worried about future conflicts, maybe you can suggest a rotation system for extra tasks. This way, everyone takes turns, and no one feels singled out or overburdened.
