In response to the pain points of traditional campus safety education in primary and secondary schools, such as the lack of teachers and curriculum standards, this service creates a campus safety education custody service system. Through custody based education, nanny based services, and integrated teaching, it effectively solves prominent problems such as who will teach, what to teach, how to teach, when to teach, and how to evaluate safety education in primary and secondary schools. This service uses one security knowledge base, one cloud service platform, one evaluation system, one security classroom, and a series of “online+offline” security experience activities to enable every student to complete a safety culture education loop of “teaching, learning, practicing, testing, and evaluating”, achieving an improvement from “I’m asked to be safe” to “I want to be safe, I know how to be safe, and I can be safe".
