"I'm sorry, Professor Zhao, I'm really busy with some stuff right now and just don't have the time, maybe next time?"
"Oh? Is that so? Then could you give me Qiao Ze's contact information so I can call and ask?"
Li Jiangao pondered for a moment, then said, "I really should respect Qiao Ze's wishes, he doesn't like to interact with people he's not familiar with. Why don't you wait, and I'll ask Qiao Ze first to hear what he thinks."
"All right then, just tell him that a professor from Yanbei University wants to meet him."
"Sure, okay!" After agreeing, Li Jiangao hung up the phone.
After a moment of closed-eyed thought, Li Jiangao felt he should still respect Qiao Ze's opinion, so he picked up his mobile phone and opened WeChat.
