General schools have school rules. Whether to punish or not depends on how your school stipulates it. You can look it up on official website in your school. There is a rule in our school: middle school students should keep a good mental outlook, they should not wear earrings or jewelry ... they should not defame the school with a bad image, which will affect the appearance of the school ... There are too many copies, which were mixed up in those years. I used to want to get a tattoo because they always said I was naive. Later, I stopped tattooing, because I was never sure whether it was a super action hero or a crayon Shinchan! alas
