It is known to all that Christmas Day is on December 25th. It is the biggest day in the western countries. But not so many people know about the White Christmas in China. The day before Christmas Day, if it snows, then the world is in white color. People are happy about that, becausethey think it means the happiness and luck. So thats the meaning of White Christmas. It always snows a lot on Christmas Eve, because it is in winter in the western countries. All the families get together and enjoy their moment while watching the white snow. What an enjoyable atmosphere for a family.众所周知，圣诞节是12月25日。在西方国家，这是最重要的日子。但是在中国却很少有人知道白色圣诞节。圣诞节前夕如果下起了雪，那么世界就会变成白色。大家都很高兴，认为这意味着幸福和好运。这是白色圣诞节的意义。圣诞前夕总是会下大大的雪，因为在西方国家，那时候是冬天。所有的家人聚在一起，赏雪，享受着家庭的温暖。这是多么愉快的家庭氛围啊。
