Quick answer for you. "NO." In Hong Kong and many civilized countries, you need to have concrete evidence. I do not see you have any proven evidence on what you have mentioned.
However, if you want to move on, please continue to read as I want to help you. Otherwise, read others' answers.
You are talking about 16 years ago. You are still bothered by the incident.
Yes, your teacher was not right to hit you on your face. Back to those days, teachers treated students like their own children and would easily get irritated if their students did not do what was told. You are not the only one. It was very common. Small students or children do not have much dignity at all. We did not even know the word shame until we get older and understand we should treat others in the way that we want to be treated.
Perhaps your teacher might not be happy as he/she felt very guilty of what he/she had done as well. Why can you not forgive him/her and have a big heart and be a happy person.
What happened to you can be a sample to yourself that you will treat others with respect.
