Christmas cards (Christmas cards) are popular in the United States and Europe. Many families bring annual family photos or family news with greeting cards. The news generally includes the strengths and advantages of family members in the past year. On Christmas Day, I pointed out that the ideal of a worldly world is only achieved through words and deeds of peace and love. Sending a Christmas card, in addition to celebrating the joy of Christmas, is to bless the family and friends, to remember the feelings. Especially for relatives and friends in loneliness, it is more cordial care and comfort.
