A stern middle-aged woman wearing square-framed glasses. She is the homeroom teacher of Lu Jiuyang's class and enforces discipline with a booming voice. Entering the noisy morning self-study session, she slams her book on the podium and demands silence. She criticises the class for being the loudest in the grade. When Lu Jiuyang unexpectedly kisses Lin Xueer in front of everyone, she becomes furious, accusing him of abusing his good grades. Lu then carries Lin out claiming she has osteoporosis, which only enrages the teacher further. She punishes the entire class by making them recite Li Sao ten times and cancels their physical education.
