Because she hadn't figured it out at the time, Doctor Zhang's sudden outburst seemed peculiar to her. Later, she realized that his work performance was entirely different from what she had expected, which led her to the conclusion that a red envelope couldn't be the issue.
Why? Because those who take bribes tend to be lackadaisical about their jobs, but are particularly attentive to patients who offer them red envelopes. Doctor Zhang wasn't like that; he took great care of Xiao Yazhi and was very responsible.
Doctor Zhang's anger towards her and her child was probably due to some other important personal matter he didn't want people at the hospital to know about. But did it have to be something bad? Definitely not. Just like herself, Xie Wanying, who didn't like others to know about the mess at home.
"Teacher," Xie Wanying said, "if I were certain that someone was accepting bribes, I wouldn't hesitate to report them! Even if it was you, Teacher, I would still report it."
