PUA (full name: strike up a conversation artist, meaning strike up a conversation artist) originally refers to a group of behaviors that continuously improve their emotional intelligence through systematic study and practice. Later, it generally refers to people or behaviors that attract the opposite sex and fascinate the opposite sex.

PUA is now developing rapidly in organizational form. It instigates people to cheat through offline training or online courses, which mainly involves chatting up (first acquaintance), attracting (interaction), establishing contact, upgrading relationships until intimate contact and determining gender relations.

In layman's terms, it is to achieve mental control over each other through brainwashing after establishing a relationship.
