The three links of health injury management are closely linked: discussion, communication, hands-on operation and personal experience.

In the first part, guide young people to discuss and recall their initial experiences, so as to stimulate young people to discuss: who broke his arm or leg, was injured in first aid, etc. Arouse teenagers to talk about self-help, adjust experience observation pictures, solve knee bleeding, and treat injured teenagers to observe questions: Friends think it is necessary to inspire teenagers to solve their fears, and need to comfort and help them talk about every treatment step and help them eliminate their fears and actively cooperate with doctors for treatment.

In the second link, the experience of young people has been expanded. The injury office first asked young people to observe the four pictures on the left and talk about the injuries suffered by their friends. Then, ask the young people to find out each kind of injury with the four pictures on the right, and draw a circle of each two pictures with the same color. Ask young people to introduce their own judgments, encourage young people to choose, guide young people to discuss, adjust their misunderstandings, enrich their fracture ability, and wipe the scalded place with a cloth. The teacher helps young people to sum up key experiences such as nosebleeds, burns, mosquito bites and falls.

The third link is to encourage children to save themselves. Please tell me what I can do, what help I need, and medical care. Encourage children to do medicine to save themselves, or inform and treat the injured body immediately to relieve the pain and make the injured part recover as soon as possible.

Help teenagers understand the injury, see self-help, enhance self-help awareness, and give comfort, help and sympathy to other injured people.
