General colleges and universities have no restrictions on candidates' tattoos, and they can apply for the exam. However, if there is a large area of tattoo pattern, a famous school like Tsinghua will not accept it, because it is incompatible with the students in the school.

Tattoos are definitely not allowed to apply for national defense students in military schools, public security and judicial organs, etc. These institutions have to carry out special physical examinations and will not accept large-scale tattoos.

Although ordinary colleges and universities have no restrictions on candidates' tattoos, they cannot be different.
