The National Open University, formerly known as the Central Radio and TV University, was established on the basis of the Central Radio and TV University and local radio and TV universities. It is a new university facing all members of society and without walls. Like other adult colleges and universities, it is mainly aimed at social workers who failed in the college entrance examination or lost their learning opportunities for other reasons, as well as on-the-job workers who need to improve their academic qualifications. This is the state's recognition of academic qualifications, which can finally be found on Xue Xin. com。
