On the night Jesus was born, shepherds watching over their flocks in the fields suddenly heard a voice from heaven telling them about the birth of Jesus. According to the Bible, Jesus came to the world to save people and became the savior of all mankind (see Matthew 1:21, "He will save his people from their sins"). Therefore, the angels used these shepherds to spread the message to more people.
Later, people imitated the angels and spread the news of Jesus' birth all over during Christmas Eve. To this day, it has evolved into the tradition of singing carols.
Christmas Eve is also considered the time when Santa Claus and similar figures in other regions distribute gifts to good children. In Italy, gifts are opened on the morning of Christmas Eve, while in the UK, Ireland, Sweden, Denmark, Norway, Finland, Portugal, and Poland, Christmas gifts are usually opened on the evening of Christmas Eve or the morning of Christmas Day. In most parts of Germany, Christmas gifts are opened on the evening of Christmas Eve (German: Bescherung). In Iceland, Christmas begins at 6 p.m. on Christmas Eve, church bells are rung, and people enjoy a family dinner together, then open gifts and spend the evening together. In North America, most families open gifts on the morning of Christmas Day. For divorced families, children may celebrate separately with either father or mother. In Spain, gifts are opened only on the morning of January 6th, the Epiphany (Día de Reyes). Many traditional Christmas stories take place on Christmas Eve.

Christmas is the birthday of Jesus Christ, the Savior, and is a holiday established to commemorate the birth of Jesus. It is because of the birth of Jesus Christ that human beings have the hope of salvation. That is why this great night was set as Christmas Eve. True peace is inner peace, a deep peace within a person's soul.
Today, Christmas Eve not only represents peace and harmony, but also the beauty of reunion and hope behind it is the reason why people love it so much. Most Western families choose to gather all members at home for a sumptuous dinner on Christmas Eve, then sit by a roaring fireplace, playing music and singing songs, sharing family happiness; or hold a unique costume party, celebrating through the night. Christmas Eve is a happy, peaceful, and joyful night of reunion, looking forward to the arrival of Christmas.
During the holiday period, Christians around the world hold grand memorial ceremonies. Christmas was originally a Christian holiday, but due to people's special attention, it has become a national holiday, the biggest festival of the year, comparable to New Year's Day, similar to how Chinese people celebrate the Spring Festival. Westerners use red, green, and white as the colors of Christmas, and when Christmas comes, every household decorates their homes with these Christmas colors.
