Winter solstice, also known as solstice, winter festival, child year, etc. It has both natural and humanistic connotations. It is not only an important solar term among the 24 solar terms, but also a traditional folk ancestor worship festival in China. The solstice in winter is the extreme point of direct sunlight spreading to the south. On the solstice in winter, the sun shines directly on the Tropic of Capricorn, which is the most inclined to the northern hemisphere and the solar altitude angle is the smallest. In all parts of the northern hemisphere, the days are the shortest and the nights are the longest.

The Winter Solstice Festival originated in the Han Dynasty, flourished in the Tang and Song Dynasties, and has been passed down to this day. Lu even said that the winter solstice is as big as a year. This shows that the ancients attached great importance to the winter solstice.
