Explanation
In South Korea, pointing with the index finger is considered rude and aggressive, as it resembles a gesture used to scold or accuse. Instead, use an open hand or gesture with your chin or head to indicate direction or a person. This is rooted in Confucian values of respect and harmony.
Local Tip
When indicating someone or something, extend your whole hand with palm up or nod your head in the direction instead of using a single finger.
