about 无法平静 de question

I read 无法平静's article for a few times, and I have a lot of questions
for us here. I want to get professional answer.

It looks like the 无法平静 herself is already an adult. So she should
be responsible for herself's behavior.

But on the other hand, her former boss, as her teacher at least morally should
be punished. It is a taboo for the teacher to have sex with their students
, especially when the teacher himself is married.

I know that such cases is very hard to get fairness in China.

But what should be the correct legal action on her teacher's behavior
if ideally the law is fairly done in China?

I want professional answer from an expert. I myself actually is getting
confused.
