The college season of Grade One has been broadcast for five times, and Liu Yun, as a physical teacher of Grade One, has naturally attracted much attention. In the last college season of Grade One, Liu Yun and the students of Grade One played a group crossing. In this crossing, Liu Yun's cross-dressing role aroused heated discussion among the audience, and both the old demon in Montenegro and Niu Wangmo performed another flavor. Liu Yun was very satisfied with his performance, while Shao Mingming said that Mr. Xiaoyun's monster costume "scared the baby to death".
