Is the winter solstice the earliest of the 24 solar terms?

Winter solstice is one of the twenty-four solar terms and one of the most important solar terms. There is heavy snow before the winter solstice (node on February 7-9, 65438), slight cold from winter to the future (node on October 4-6, 65438/kloc-0+February 2 1), and node on February 23, 65438+February 23.

Name explanation

The ancient saying about the winter solstice is: when the cathode comes, the yang begins to grow, the sun goes south, the day is short and the shadow is long, so it is called "winter solstice".

Astronomy regards the winter solstice as the beginning of winter, which is obviously late for most parts of China. During the winter solstice, the average temperature in the northwest plateau is generally below 0℃, while it is only about 6℃ to 8℃ in the south. However, in the southwest low-altitude valley area, even in the coldest local165438+ in early October, the average temperature is still above 10℃. It can be said that autumn goes and spring comes, and there is no winter all year round.
