SanJiuTian explanation:

There is a proverb in China called "Count nine winters", and the seasons are counted from winter to nine days. The specific calculation method is to start counting from the winter solstice (around February 22nd of today's Gregorian calendar 12) (the winter solstice is called "September 9th", which means that the cold weather starts counting for nine days), every nine days is called "September 9th", the first nine days are called "September 19th", and the last nine days are called "February 29th", and so on until counting. At this time, winter has passed and spring has arrived.

Of course, the pace of spring varies from place to place. Although it has reached nine, the vast northern region has not entered the meteorological spring. Spring usually appears in the south of the Yangtze River in the first half of March, in the north of China from the second half of March to the first half of April, and in the north of the Great Wall from April to May (the average daily temperature is above 10℃ for five consecutive days). See "Spring".
