The invigilator and head teacher of Tao Shushu's class. He is hostile toward Tao Shushu, accusing her of pretending to sleep during exams and disrespecting exam discipline after she previously scored full marks in physics multiple times. He forcibly removed her from the exam room with ten minutes remaining and made her stand in the hallway. He glared at Tao Shushu through the door crack when other students were submitting their papers.
