There is no such thing. With regard to skin examination, it is indeed necessary to take off your clothes and have a physical examination when entering the university, but the main purpose is to observe whether there are skin diseases (infections) and so on. As for tattoos, it is personal freedom and will not interfere. PS: The one on the first floor said that the college experience was actually very relaxed. Personally, I disagree. At least the university where I work is very formal when we enter the school, and the doctors for physical examination will not be too lenient. I don't know if the people on the first floor went to college or what university they went to. . .
