Although tattoos themselves won't hurt others, people are social people. Your every move is inextricably linked with others. You will be disgusted by your parents, teachers, classmates and even strangers, making them think that you are different and like a gangster, even if you think tattoos are cool, handsome and cool.
It takes courage and strength to fight against everyone. Without extraordinary skills, you can't beat them at all. Not only can you not fight, but you will also lose miserably. Therefore, following the socialist core values is the right way.
For you, for me, I hope you will adopt it.
