Who can explain the geographical significance of the winter solstice in detail?

Winter solstice, commonly known as "Winter Festival", "Dragon solstice Festival" or "Children's Day". Winter solstice is an important solar term in the 24 solar terms of the lunar calendar, and it is also a traditional festival of the Chinese nation. The winter solstice is a "winter festival", so it is considered as a big holiday in winter. In ancient times, there was a saying that "the winter solstice is as big as a year". In ancient times, people wandering in other places had to go home for the winter festival at this time, which was called "having a home at the end of the year". In ancient times, there was a saying that "the winter solstice will bring the sun", that is to say, from the winter solstice, the spirit of the sun slowly began to recover. [ 1][2]

The winter solstice is June 65438+February 2 1 ~ 23 in Gregorian calendar every year. It is worth noting that around the winter solstice, the earth is located near the perihelion, and its running speed is slightly faster, resulting in that the time of direct sunlight in the southern hemisphere is about 8 days shorter than that in the northern hemisphere in a year, so the winter in the northern hemisphere is slightly shorter than that in summer.

The ancients said: When the cathode arrived, the yang began to grow, the sun went south, the day was short and the shadow was long, so it was called "winter solstice day". The ancients believed that from the winter solstice, the sun be the spirit of heaven and earth began to flourish, that is to say, the next cycle began, and the sun be the spirit of heaven and earth rose to the winter solstice, which was a "good day" [3][2].
