Which solar term will be shorter in a day?

The winter solstice is the year with the shortest day and the longest night in the northern hemisphere. After the solstice in winter, the days will get longer day by day. The ancients said this about the winter solstice: As soon as 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 "the winter solstice". After the winter solstice, the climate everywhere has entered the coldest stage, which is often called "entering the ninth". There is a saying in China that "the cold is in the third day, and the heat is in the dog days".

Winter solstice is one of the twenty-four solar terms and one of the most important solar terms. Winter solstice is a solar term divided by astronomy, which was called "short day" and "short day" in ancient times. On the solstice in winter, the sun is at 270 degrees of the yellow meridian, and the sun shines directly on the tropic of Capricorn, which is the shortest place in the northern hemisphere in a year. Accordingly, the winter solstice in the southern hemisphere has the longest day. "Twenty-four solar terms" said: "On November 15th, the gas storage finally came to an end." . "Tong Wei Xiao Zhu Shen": "The fifteenth day after the heavy snow is the winter solstice, in mid-November. Yin and Yang began, and the sky went south and grew up. " "Zunxian Manuscript" said: "The day is south, the day is short, and the shadow is long, so it is called the winter solstice. People who' want' are extremely excellent. " It can be seen that our ancients have long known this.

There is no 10 hour from sunrise to sunset in most parts of southern China. From winter to the future, as the earth orbits the sun, the direct sunlight belt gradually moves northward, making the days in the northern hemisphere gradually longer and the nights gradually shorter.
