Christmas, also known as Christmas, is translated as "Christ Mass", which originated from Saturnalia, a festival in ancient Rome to welcome the New Year, and has nothing to do with Christianity. After Christianity prevailed in the Roman Empire, the Vatican drifted into the Christian system to celebrate the birth of Jesus. But Christmas is not Jesus' birthday, because the Bible does not record the specific date of Jesus' birth, nor does it mention the existence of such a festival, which is the result of Christianity absorbing ancient Roman mythology.

Sending Christmas cards is very popular in America and Europe. Many families attach annual family photos or family news to their greeting cards. News generally includes the strengths and specialties of family members in the past year. At Christmas, it was pointed out that the ideal of one world and one world can only be realized by peaceful and kind words and deeds. Sending Christmas cards is not only to celebrate the joy of Christmas, but also to bless relatives and friends to show their memory. Especially for lonely relatives and friends, it is kind care and comfort.

An China idiom means that timely winter snow indicates a bumper harvest in the coming year. This is a harbinger of a bumper crop in the coming year. As the saying goes,' snow will bring a good harvest', and next year's wheat harvest will be very good.

It's cold in winter, and the snow often doesn't melt easily. The snow covered on the soil is soft, and there is a lot of stagnant air hidden inside. Air doesn't transfer heat, just like covering a quilt for crops. No matter how cold it is outside, the temperature below will not drop very low. Covered with winter snow, it is not easy to attract pests.
