"Classmate, can I have your contact information?"
"No."
Cen Yu gritted his teeth, unscrewed the mineral water bottle in his hand, and poured the water directly on the other party, "Ah, I'm sorry, classmate! Your clothes must be very expensive, and I must compensate you for this. Why don't you leave my contact information!" He quickly took out the pen and paper in his schoolbag, "Classmate, do you use Facebook or WeChat? Forget it, just write them all." He wrote down his Facebook, WeChat and mobile phone number, left his name, and handed it over.
