Open education belongs to adult education and is also a part-time education. It is different from the traditional general and adult higher education, and implements the learning system of "lenient entry and strict exit" and "complete credit system". After students pass the entrance qualification examination and entrance level test, they can register to obtain their school status and enter the corresponding professional courses. Learning mainly uses written textbooks. Candidates can log on to the remote online teaching platform through the Internet, order and download online teaching resources at any time for autonomous learning, and can also interact with teachers and classmates to ask questions and discuss exchanges, which is very suitable for on-the-job candidates to choose.
