A sense of security means a psychological need for stability and security, which belongs to an individual's inner spiritual need. The sense of belonging means an internal connection between an individual and the group to which he belongs, and it is an individual's demarcation, identification and maintenance of a special group and its subordinate relationship.

The sense of security and sense of belonging are also different:

1. The sense of security is mainly reflected in the spiritual level, which is a premonition of possible physical or psychological dangers or risks, as well as the sense of strength/powerlessness of individuals in dealing with things, which is mainly manifested in the sense of certainty and controllability.

2. The sense of belonging is generally a sense of responsibility. When the sense of responsibility reaches a certain level, it will produce a sense of belonging to something. The sense of belonging is divided into the sense of belonging to people, things, families and nature. There is a strong sense of belonging to people in adolescence, to career and family in middle age, and to nature in old age.
