PUA (master of picking up girls) behavior refers to a strategy and skill used by men when looking for heterosexual partners, also known as "chatting up". The purpose of this behavior is to attract the attention and recognition of the opposite sex, so as to achieve the purpose of establishing a love relationship.

However, PUA behavior is now widely belittled and criticized because it often involves deception and manipulation, and sometimes even sexual harassment.

In the digital age, the behavior of PUA has also changed. Now there are some controversial PUA training courses and social media numbers that publish content about how to attract the opposite sex and make yourself more attractive. These contents often cover up many negative behaviors.

Generally speaking, PUA behavior is an unhealthy behavior. Establishing a truly healthy relationship should be based on honesty, respect and understanding, not through deception and well-planned skills. Emphasizing self-improvement and being honest with yourself and others is the foundation of a healthy and sustainable love relationship.
