One day during class break, Zhang Zetao went downstairs to call Zhang's mother, and Zhu Weijun went with him as his deskmate.
Arriving at the phone, Zhang Zetao picked up the phone, swiped his student card and pressed the number.
Zhang Zetao: "Hey, Mom."
Zhang's mother: "…who are you…"
Zhang Zetao: "............"
Zhu Weijun, with sharp ears on the side: "Hahahahahahahahaha!!!"
Chi Yanyan and Chi hope, who later learned about the incident: "Hahahahahahahahahahahahahahahahahahahaha!!!"
