Today the winter solstice, the winter solstice sun spring again

The Winter solstice, also known as the South solstice, Winter Festival, and Sub-year, has both natural and cultural connotations. It is not only an important solar term among the 24 solar terms, but also a traditional Chinese folk festival for ancestor worship. The Winter solstice is one of the four eight festivals, is regarded as the winter festival, in the ancient folk "winter solstice as big as the year" doctrine.

Some ancient Chinese literary works divide the winter solstice into three periods: "The first period is earthworm formation; Two Hou moose horn solution; Three waits for the spring to move." It means that the earthworm in the soil is still curled up, and the moose feels the Yin gradually receding and dishorning. Since the direct point of the sun returns to the north after the winter solstice, the sun's round-trip movement enters a new cycle, the sun's height rises since then, and the day grows day by day, so the spring water in the mountain can flow and warm
