Children in the city attend school according to their grades, but the village isn't as particular about such matters.
Over twenty kids of mixed ages learn together, progressing at different paces, with the teacher covering several points in a single lesson.
Some children, having already learned the material, whisper among themselves below.
Those who haven't learned can't hear well due to the noise and can only stare intently at the teacher's lips.
The first class was taught by the only female teacher, Sun Yueyue.
With her apple-shaped face appearing kind and friendly, the kids weren't too scared of her.
Even as Sun Yueyue repeatedly stressed not to talk, there were still children chattering away.
With no choice, Sun Yueyue walked down from the podium again and again, asking the chatty kids to move their stools to the last few rows, while those who hadn't learned moved to the front.
Yue Qingqing and Yue Xiaohu were arranged to sit in the first row.
