Drowning prevention education: teach children the "Six Nos and One Know" - how many have you taught as a parent?

Summer is the time when temperatures are high and rainfall is extremely irregular. The summer sun makes it just right for sleeping, and especially at this time, educating students about drowning prevention is not only the responsibility of schools and families, but also something every one of us should do.
Teach children to follow the "Six Nos and One Know." As a parent, you should rightfully do this: No. 1 means: do not go swimming privately without a parent or teacher leading you.
No. 2 means: do not go swimming with others (classmates) without permission.
No. 3 means: do not swim in waters without safety facilities and without rescue personnel.
No. 4 means: do not swim in unfamiliar waters.
No. 5 means: on the way to and from school and during holidays, do not play in the water at rivers, reservoirs, ponds and other such places.
No. 6 means: students who are not familiar with swimming must not go into the water on their own to rescue others. (In particular, educate children to avoid blindly trying to rescue a companion by holding hands when they are drowning; they should rescue wisely and immediately seek help from an adult.)
One Know means: teach students to learn basic methods and skills for self-protection and self-rescue.
