In terms of verbal attacks, comparison is always one of the simplest ways to make someone uncomfortable or even angry, regardless of their gender.
"You're not even as good as XXX..."
"XXX is not only prettier but also gentler than you..."
Or to be more tactful...
"XXX thinks that because of you, this project is difficult to succeed..."
In short, these three question marks highlight Chen Zhuoyang's complex feelings at the moment. He feels more confused than disappointed.
Someone else might think Qiao Yu is talking nonsense. But Chen Zhuoyang actually didn't go far; he's teaching at the School of Mathematics at Jinzhou University, right next to Beijing.
Some news can still be picked up.
Not to mention that he's more aware than anyone of Qiao Yu's status in the eyes of Elder Yuan and Director Tian.
