Historical evolution of the winter solstice
The concept of "Winter Solstice" appeared as early as the Yin and Shang Dynasties, but at that time people called the Winter Solstice as "Solstice", "Nannan", "Southern Solstice"."Sun", etc., these words have been found in the oracle bone inscriptions of Yin Ruins.The earliest appearance of the "Winter Solstice" may be because the ancients were too sensitive and concerned about this date - after the Winter Solstice, the days are getting longer and longer, and after a period of severe cold, the weather will gradually turn warmer.
During the Qin and Han Dynasties and before, of the 12 solar terms in a year, the winter solstice was the starting point, and "Xiao Han" was the starting point of the 12 solar terms.Therefore, Sima Qian’s "Historical Records:Law Book" said:"Qi begins with the winter solstice, and the cycle begins again and again." At that time, the official held a grand sacrificial ceremony on the winter solstice.According to "Historical Records Calendar", in the seventh year (104 years ago) of Emperor Wu of the Han Dynasty, Liu Che used the "Winter Solstice" as the beginning of the year, and changed the year name, calling the year "Tai Chu Yuan Year".At the same time, an edict was issued, requiring everyone to celebrate the "Winter Solstice Year".
The "Three Rites and Righteousness" written by Cui Lingen, a Liang native of the Southern Dynasty, said:(Winter solstice) has three meanings:one is the arrival of the negative pole, the other is the beginning of the yang energy, and the third is the day that travels south, so it is called the winter solstice."It is also believed that the winter solstice is the weakest day of the year for yang qi, after which the yang qi gradually rises.

The winter solstice is the 22nd solar term in China’s twenty-four solar terms, when the sun reaches 270° of the ecliptic longitude.It is recorded in the "Copyon of Ke Zun Xian Du" "When the negative pole arrives, the yang qi begins to arise, the sun arrives in the south, the sun is short, and the sun’s shadow is long, so it is called the winter solstice."The sun directly hits the Tropic of Cancer on the winter solstice, with the shortest day and longest night in the northern hemisphere.As early as the Spring and Autumn Period more than 2,500 years ago, China had already observed the sun with Tugui and determined the winter solstice, which is the earliest among the twenty-four solar terms.The one formulated, the time is from December 21st to 23rd of the Gregorian calendar every year.
