At Sunshine Middle School, a place filled with laughter and cheerful chatter, the mischievous A Dong and his classmates get up to one hilarious bit of everyday school life after another. Snack-loving Li Xiaopang is always battling treats in class, top student Zhang Tingting tries to keep everyone in line but keeps getting dragged into their antics, and Wang Kugai loves showing off but can never stay cool for more than three seconds before making a fool of himself. Timid Chen Mengmeng often causes chaos over the tiniest things. These friends, each with their own quirks, turn the classroom, playground, cafeteria, and every other corner of school into the setting for daily laugh-out-loud adventures. With their youthful energy and absurd antics, they create a string of joyful memories from their school days.
