The process of three prevention education in grade two is as follows:

1. Visit national defense fortifications-underground reservoirs, war-ready grain depots, wartime protection facilities, etc.

2. Military knowledge education-introducing the current world military environment and new weapons and equipment.

3. Watch war videos-the characteristics of local wars under modern high-tech conditions.

4, "three defenses" knowledge education-basic knowledge and protection knowledge of nuclear, chemical and biological weapons.

5. Visit the flag-raising ceremony of the military camp.

6. Watch the "Three Preventions" drill-professional chemical defense soldiers demonstrate the correct protective actions of indoor and outdoor personnel under nuclear conditions and how to wear chemical defense suits correctly.
