F.4D at Yucai Academy is the most stubborn class in the whole school. Not only do they fail exams, but they also often prank their teachers. Countless teachers are angered by this group of mischievous students. The most ancient and eccentric among them is the young leader Zhang Yijian (played by Zhang Weijian), who runs rampant on campus, even including Director Qin (played by Wu Weijian)
