"새해 인사" refers to the traditional New Year's greetings in Korea. It is a way for people to express their wishes for health, happiness, and prosperity in the coming year. These greetings are often exchanged among family, friends, and colleagues during the Lunar New Year celebrations. During this time, people may say phrases like "새해 복 많이 받으세요," which means "Wishing you a lot of luck in the New Year." In addition to verbal greetings, it is common to give small gifts or money, especially to children, as a symbol of good fortune and blessings for the year ahead.
