Knowing how to properly greet someone in Korean is crucial due to the high value placed on respect and politeness in Korean culture. For girls, the most common greeting is "annyeonghaseyo," which means "peace" and is a formal and polite way to say hello. Intonation, bowing, and eye contact also play important roles in conveying respect and politeness. In business settings, formal language and behavior are expected, while social settings may allow for more casual language and gestures depending on the relationship between speakers. Cultural awareness is key in building positive relationships with others from different backgrounds.
