"You already know my cell phone number."Jiang Tong hung up the phone. She put her cell phone back into her pocket, turned around, and opened the door as she said, "I didn't leave you my contact information because firstly, your cell phone number is in my brain, so I can contact you. Secondly, I was in a hurry at that time, so I forgot to give you my contact information. It was my mistake." She pushed the door open, then gestured to Ji Lanzhou, "Come in and have a seat."
