Counting to nine is one of the popular customs in China. Counting nine means counting from the date of winter to Sunday (also called counting from winter to Sunday), counting nine every nine days, and so on. As the saying goes, "it's hot in three days, cold in four or nine days", and the coldest period in a year is "three or nine days". Count to nine until the eighty-first day, when the peach blossoms open at nine o'clock. At this point, the cold has gone and the weather is getting warmer.
Due to the vast territory of China, the climate varies greatly from place to place. Only parts of China, not all parts of the country, correspond to the winter solstice "9981, nine peach blossoms, deep spring and warm days", and some cold areas have no breath of spring.
There is a folk saying, "The solstice in summer is three years old, and the solstice in winter is nine years old." The number nine method is passed down from mouth to mouth in some places in China, which has a history and lacks records. As for when it originated, the exact information is available. The ancients followed the example of the sky, took the image of the land, set solar terms to know solar terms, and made calendars to know time changes; Qi is divided into yin and yang, everything flows, man and astronomy are interlinked, and Tao becomes nature.
In China's traditional philosophy, the rise and fall of Yin and Yang symbolizes the arrival of warmth and the departure of cold. In traditional culture, nine is the limit number, which is the largest, most and longest concept. Nine nines is eighty-one, which is the "maximum" number. Nine is the number of "the sun", also called, and nine is the largest number. "Sunrise" accumulates over time, indicating that Yin Qi is decreasing day by day, and it is exhausted for nine times, indicating that the cold is getting warmer and the "spring is deep". It's time for spring ploughing.
The method of calculating cold and warm by number nine is suitable for areas where the temperature changes obviously from winter to around in China. The calculation of temperature and warmth changes is accurate to days. Judging from the number of days from winter to Sunday, the coldest periods are "March 9 and April 9", while counting to "998 1 day" is a warm day in late spring.
There are also some places that count to nine from the day of winter solstice. In some cold areas, the temperature in winter and spring is below zero degrees Celsius for a long time in the ice and snow, and the temperature change is not obvious from winter to around. "Nine days" is not much different from the temperature. For the convenience of counting nine, the days from the winter solstice, that is, the winter solstice, are called "nine-ninth" and every nine days are "nine-ninth".
