In recent years, the number of students infected with AIDS in tertiary institutions has been increasing year by year, and the reasons for this are manifold. If the Government and the education sector can take effective measures to increase publicity and protection, it is possible to effectively control and spread the disease. In such a complicated society, how can we protect and educate our children? Parents are duty-bound to do so. First of all, they should establish equal friendship with their children and let them understand the charm of classical culture. Secondly, advise your children to make good friends and mentors. Again, collect influential news reports and recommend them to your child so that he can talk about his ideas. Finally, advise your child not to share personal belongings with others when studying and working outside, even if it is the best relationship. If parents do their job right, even if the child is in a complicated college or university, he or she will be able to clean up his or her act.
