It is understood that there are no laws and regulations in China that prohibit people with tattoos from going to college. However, some universities will have their own regulations prohibiting students from displaying tattoos or having obvious tattoos on campus. Therefore, if you have tattoos, I suggest you know the relevant regulations of the target university in advance.
In addition, whether tattoos affect admission depends on the specific situation. If your tattoo is too exaggerated or has a bad meaning, it will adversely affect your admission. However, if your tattoo is simple, it will not affect your appearance, school education order and your admission.
