After He Yiran finished speaking, everyone started to find something to do—Luo Yingying swept and mopped the floor, she and Yan Keke wiped down the desks and beds, and He Yiran took care of cleaning the balcony and restroom.
Everyone divided up the work and kept busy, and whoever finished first would go help someone else. Since school hadn't officially started yet, nobody fussed too much about it; later on, when things weren't as dirty, they'd just take turns with one person doing chores a day.

With so many people, cleaning up became pretty easy. They were done before long, and the rest just had to wait until things dried, so Yan Keke suggested, "Let's go to the campus Supermarket and buy some daily necessities. I came here and brought nothing. Do you guys need anything?"
"Yeah, I need to buy stuff too. I didn't bring anything," said Mei Mengzhen.
