The Outline of the National Unified Examination for Enrollment of Ordinary Colleges and Universities is a legal document on the proposition of ordinary college entrance examination, which should be strictly observed by the examination center of the Ministry of Education and the relevant provincial and municipal enrollment examination institutions.
