In Africa, Christmas Day begins with groups of carolers (欢唱颂歌的人) walking to and from through the village, along the roadway, by the houses of the missionaries (传教士), singing the lovely carols known to the world around. Often people may be awakened by a group of carolers beginning to gather at the house of worship (敬神活动). They return home to make final preparations as to the clothes one must wear and also as to their offering for the Christmas service.The most important part of their Christmas worship service is the love offering.
