It is found: (1) there were significant statistical differences in terms of gender, school type, grade, urban or rural areas, and parents’ educational level. (2) awe, self-perception size and bullying behavior were significantly correlated between one another; Life awe, legal awe and self-perception size could significantly and negatively predict school bullying.
