Not even summer yet and already worried about... drowning

Ms. Tam was taking care of the rice in her field by the roadside when she heard a villager passing by calling:
- Is it someone like Tam's family? I heard that your son and his friends drowned on the way home from school, luckily they were saved by a worker at the river. Everyone is gathering on the riverbank. Come out now!

Hearing that, Ms. Tam frantically grabbed her bicycle and rushed to the riverbank, her heart burning with anxiety. She panicked even more when she saw her child's bicycle and school bag lying haphazardly on the grass.
- My son! Are you okay?
She screamed and rushed through the crowd. On the grass, her son Hoang lay straight, his face pale, eyes closed, breathing weakly. Seeing her so emotional, a man in wet clothes pulled her out:
- Are you the child's mother? Don't panic. His life and death moment is over. He just received first aid and is breathing again, but he's still tired. Let him rest for a while.
One lady said:
- That's right! The fact that the baby is alive is a blessing for your family. Go home and slaughter a pig to celebrate. He was the one who saved your child. When he pulled the baby out of the river, he had to carry the baby upside down and run around the beach dozens of times to let the water out, then give him CPR.
Ms. Tam stopped crying and turned to the man:
- My family is grateful to you. If it weren't for you today, my child probably wouldn't have survived.
Gentleman:
- Others in the same situation as me would have done the same. When I was weeding corn on the field, I saw a group of kids coming home from school and going to the river to bathe. I warned them but they didn't listen. After this incident, you and other parents must pay close attention to educating your children. Even if they know how to swim, they should not go to rivers or lakes to bathe because those places are very dangerous.
One lady added:
- That's right, recent drowning incidents are mainly due to young, hyperactive children who are too busy playing and ignore warnings of danger.
Another added:
- It's not even summer yet and you're already worried about drowning... It's best for families to take their children swimming in public pools. The water there is both hygienic and safe because there are lifeguards and coaches to guide the children in proper swimming techniques.
