There was a student standing in the corridor with his head lowered. Teacher Zheng next to him kept talking, "Cheng Kang, how many times have I told you. If you have any questions, ask the teacher after class, and don't interrupt the teacher's train of thought. Why don't you understand? There must be one teacher in a threesome, so be humble."
The boy named Cheng Kang heard the teacher's hysterical expression and the corners of his mouth curled up nicely, and said in a ruffian way: "Old Master Kong also said that there is no greater virtue than being ashamed to ask questions." He quoted scriptures and spoke clearly.
He shook his head like an old scholar, and Fang Ci became happy when he heard a "poof" sound.
