What does a winter solstice as big as a year mean?

In ancient China, people paid special attention to the winter solstice festival. "Hanshu" records: "The sun shines on the winter solstice, and the monarch is long, so congratulations." During the Tang and Song Dynasties, there was a saying that the winter solstice was as big as a year, and "Miscellanies of Wuzhong Chronicles" recorded: "The winter solstice is as big as a year, and the county people attach the most importance to the winter solstice." At the Winter Solstice Festival in Lin 'an, the capital of the Southern Song Dynasty, the government hosted a banquet to entertain guests. According to the careful "Old Wulin Stories", "The winter solstice will be celebrated and arranged by the imperial court, just like Yuan Zhengyi." This day is also the day when the Emperor offered sacrifices to God. "Book of Rites" says that "the garden mountain worships the gods" and that "the five emperors, the sun, the moon and the stars are worshipped in the suburban altar on the winter solstice". "Quasi-Nanzi" also records that "on the solstice of winter, the son of heaven led the three officials to welcome the New Year".

Ancient people in China had the custom of celebrating the winter solstice. People think that after the winter solstice, the days become longer and longer and the sun rises. This is the beginning of a solar cycle and an auspicious day, which should be celebrated. The ancients believed that by the solstice of winter, although it was still in the cold season, spring was not far away. Everyone who goes out at this time will go home for the winter vacation, which indicates that there will be a home at the end of the year. People in Fujian and Taiwan believe that the annual winter solstice is a festival for family reunion, because it is a day to worship ancestors. Going out and not coming home is a person who denies his ancestors.
