A triad is a group of three individuals who come together for a common purpose or interest. This term is often used in various contexts, including social groups, business partnerships, and even in criminal organizations. In a triad, each member typically plays a distinct role, contributing to the group's overall dynamics and objectives. In some cultures, particularly in Chinese society, triads refer to secret societies that have historically been involved in organized crime. These groups often have a hierarchical structure and engage in various illegal activities. However, not all triads are criminal; many simply represent close-knit friendships or collaborative efforts in different fields.
