Introduction of winter solstice
On the day of winter solstice, the longitude of the sun is 270, and the sun shines almost directly on the tropic of Capricorn. Our northern hemisphere has the shortest days and the longest nights, and it has begun to enter several cold days. Astronomy stipulates that this day is the beginning of winter in the northern hemisphere.
From winter to the future, the direct sunlight position gradually moves northward, and the daytime in the northern hemisphere gradually becomes longer. The three stages of winter solstice were in ancient China, and the winter solstice was divided into three stages.
Solstice of winter: wait for earthworms to knot; Two-phase angular solution; Wait for the spring to move. Earthworm knot refers to the earthworm crouching in the winter solstice, the angle of view is that Yin Qi gradually recedes, and the angle of view is solved in the winter solstice, and the spring movement is the spring flow in the winter solstice.
The ancients thought that every five days was a waiting period. Earthworms tied knots from winter to the sun, elk horns untied on the fifth day, and spring moved on the fifth day.
According to this time, we can calculate the start and end time of each period of winter solstice.
Traditional Wonton Noodles from Winter Solstice to Japan;
There used to be a saying in old Beijing that "winter solstice wonton, summer solstice noodles". According to legend, during the Han Dynasty, the Xiongnu in the north often harassed the frontier, and the people were restless. At that time, there were two leaders, Xiongnu tribe and Tun tribe, which were very cruel. The people hated it, so they wrapped it into a corner with meat stuffing and called it "wonton" with the sound of "muddy" and "swallowing".
