The guard had been working at that school for decades. That was the first time the school had fired a teacher so casually for having questionable moral issues.
It was a small community, and the teachers' files were well-documented in the education bureau. If the school fired Ye Xueli for being morally unfit to teach the children, she would not be able to find another job as a teacher.
No school would want to hire a teacher with bad morals.
The guard thought carefully and said, "Miss Ye, you must have offended someone. You must have really offended them. Otherwise, they wouldn't have done that to you for no reason. I can give you some advice. Think about who you've offended recently. Go and apologize. Isn't your father a colonel? A senior military officer? Tell your father to help you quickly."
