Third, a primary school in Guangzhou: self-defense teaching with fun and practicality.The way this primary school integrates self-defense into physical education class is very interesting. They use gamification teaching methods. For example, in the physical education class in the lower grades (Grade 1-3), teachers will design some games similar to "small animals avoid danger". Divide the students into groups. Students in each group play small animals, while students in the other group play dangerous "hunters". "Small animals" need to use simple self-defense actions learned in class, such as fast running and sideways avoidance, to avoid the capture of "hunters".In the senior grades (grades 4 to 6), the teaching is conducted by means of scenario simulation. For example, simulating a scene where a stranger pulls on the road, the teacher will guide students how to deal with the danger by shouting for help and using schoolbags and other items for self-defense. This interesting and practical teaching method allows students to learn self-defense in a relaxed and pleasant atmosphere.

At the same time, the course also combines some practical skills of modern fighting, such as the basic boxing methods such as straight boxing and hook boxing, as well as the wrestling method of Sanda. In addition, a special course on women's self-defense is set up to teach some simple and effective self-defense skills according to the physiological characteristics of female students, such as throat attack and eye attack against male attackers and escape skills by using the flexibility of female bodies.Judging from students' feedback, this course is very popular. In the course evaluation of each semester, the satisfaction degree of this self-defense elective course is above 90%. Many students said that after learning self-defense, not only their physical fitness has been improved, but also they feel more secure when they go out alone.
