Affected by the epidemic, teachers, students and staff in primary and secondary schools across the country had an unforgettable special time. In this environment, the teaching order has been disrupted, and network education has ushered in a rare opportunity for development, and teachers and students have more frequent contact and use of the Internet. In addition to online teaching, more and more students collect information, communicate, share and express themselves through the Internet. This puts forward higher requirements for media literacy education.

Improving media literacy education, especially relevant education for students, is an effective way to promote a healthy online lifestyle. In fact, the government and enterprises have made a lot of efforts to protect the youth network and improve their media literacy education. But this problem still exists, because most network protection measures need the cooperation of parents. If parents lack the corresponding awareness, the relevant measures of the government and the technical means of enterprises will not be effective. Only the strategic mode of joint efforts can improve teenagers' network literacy and comprehensive quality.

The large-scale application of online education during epidemic prevention and family isolation highlights the important role of the Internet in teenagers' study and life, and is also a test of minors' network literacy. The cultivation of network literacy system must be supported by the overall curriculum design and the improvement of teachers' quality. In the future, we can take network literacy as the basic course of popularizing compulsory education, increase the pre-job training and on-the-job training of teachers, encourage qualified schools to independently develop network literacy courses, and ensure that minors can receive network literacy-related training systematically and reasonably. At this time, it is necessary to strengthen the family's parent-child guidance for teenagers to surf the Internet, strengthen family participation, grasp the development goal of minors' physical and mental health, give full play to the positive role of network literacy in the growth of minors, and create a healthy network environment for the whole family.

It is necessary to give full play to the positive role of Internet enterprises, form industry self-discipline and norms, make Internet enterprises pay more attention to the improvement of minors' network security and network literacy, earnestly fulfill their corporate responsibilities and self-discipline and self-inspection norms, actively cooperate with the supervision and management of government regulatory authorities, establish industry self-discipline and self-discipline rules conducive to the improvement of teenagers' network literacy, and create a safe and healthy network environment for teenagers from the source.
