2. "Sanjiu" refers to the third "nine days" after the arrival of the winter solstice, that is, the nineteenth day to the twenty-seventh day after winter. It should be noted that "the third nine days after the winter solstice" refers to "Sanjiu", that is, the day when Sanjiu intersects with Jiu Si, not Sanjiu, so Sanjiu is nine days instead of one day.

March 9th is the lowest temperature in the whole year. From the beginning of the winter solstice solar term, the growth rate of sunlight gradually slows down. During the period from winter solstice to "March 9", the average daily daylight time only increased by one minute. In addition, due to the slow increase of the angle between the direct angle of the sun and the ground, the daily heat budget of the ground is still in a deficit state, the northern hemisphere will continue to dissipate heat, and the ground temperature will continue to drop, resulting in a very cold climate during this period.
