Marriage is not for the individual but rather for the desire of the family. If one decides to get married, they must get consent from the whole family. In the past it was generally considered a taboo for a man and a woman to marry if they both have the same last name from the same ancestor.
Korean Christians celebrate Christmas similar to the way it's celebrated in the West, but since it's primarily a religious holiday in Korea, there is considerably less fanfare and presents. Some families do put up Christmas trees, people exchange presents, and stores do put up holiday decorations, but the festivities start much closer to Christmas day. Families may attend mass or a church service on Christmas Eve or Christmas day (or both), and caroling parties are popular for young Christians on Christmas Eve.
Seollal is Korean Holiday that falls upon the beginning of the lunar calendar marking the new Lunar Year. Korean New Year lasts about 3 days, typically on this day Koreans return home to visit family and some dress up in Hanbok(or traditional Korean Dress) for the celebration. Some Koreans travel to Gangneung and Donghae in Gangwon Province to see the first rays of the New Year’s sun. Tteokguk(soup with sliced rice cakes) is a traditional korean food that is customarily eaten on Seollal. Sebae is a traditionally observed activity, children wish their elders a happy new year by performing one deep bow and parents usually reward this gesture with new years money or pocket change and words of wisdom.
