"Hey, Teacher Nanfang wants you to go to his office."
"Hey, Teacher Nanfang asked you to help me with tutoring."
"Hey, Nanfang, I've improved by 200 people this time, so I'll treat you to dinner."
"Hey Nanfang, you said that as long as I get a higher grade than you, you will promise me anything. Nanfang, please be my wife." A bad student from the north, a ruffian, a good student from the south, a sweet short story.
Intention: North goes against the south and goes along
