"세뱃돈" is a traditional Korean custom where children receive money from their elders during the Lunar New Year, known as 설날. This practice symbolizes good wishes for the new year and is often given in small envelopes. The amount can vary, but it is usually a modest sum. The act of giving 세뱃돈 is accompanied by a formal bow, called 세배, where children show respect to their elders. This exchange reinforces family bonds and teaches children about gratitude and respect within Korean culture.
