A vast area. Potential courses cover all aspects of school life except explicit courses in content, involve every corner of the school in space, accommodate all teachers and students in personnel, and have a wide range;

Diversity. School life is rich and colorful, practical activities are polymorphic and diverse, and the potential courses infiltrated into it are also diverse;
