First, keep in mind that the "Four Knows" require parents to know four things about their children: knowing where to go, knowing their companions, knowing when to come back, and knowing the contents.

Second, educate children "six noes"

(1) Don't swim in the river without permission.

(two) do not travel with others without authorization.

(3) Don't swim without the guidance of parents or teachers.

(four) do not swim in waters without safety facilities and ambulance personnel.

(5) Don't swim in unfamiliar waters.

(six) students who are not familiar with water are not allowed to go into the water for rescue.

Third, teach children "for a while"

Parents are requested to cooperate with the school to continuously strengthen the education of children's safety awareness and self-protection awareness, and teach children to master the basic methods of self-care, mutual rescue and help. In addition, I hope that parents should take good care of their children and always pay attention to your side. If there are minors swimming, paddling and playing in dangerous areas such as ponds, rivers and reservoirs without guardians, please stop them in time.

At the same time, the Provincial Department of Education also issued a letter to students from the Hainan Provincial Department of Education, hoping that students must memorize and achieve the "four things in their hearts" and "six noes" and rescue them correctly.
