This has happened to many people. Although I have been in such a situation once. When I went to class in class 10 after ninth grade, such an incident happened to me. Actually, it is a very tragic incident that you were beaten with a stick on the first day. Our teachers never understand this. Even if you are very good, besides, you are new, even if you could, you did not understand the language. For this, it is actually very bad that he behaved like this for the first time. Still, you did well, it is actually appreciated. Best wishes
