Fraternity refers to an organizational form by means of emotional communication, which aims to achieve mutual understanding between internal managers, employees and members of social organizations through parties and activities. Friendship activities usually involve multiple units or individuals, so that everyone can exchange and understand each other and promote exchanges and cooperation.

Although sororities usually include communication between men and women, they are different from blind dates because sororities attach more importance to parties and activities than to establishing love relationships. In addition, fraternity is usually an activity organized by social organizations or enterprises to achieve internal communication and cooperation, while blind date is more to find the right object.

Generally speaking, a fraternity is a gathering or activity between the internal managers and employees of social organizations or enterprise organizations and members of social organizations, while a blind date is a social activity aimed at finding a suitable partner.
