The Winter Solstice Festival
There was a saying in ancient China, "The Winter Solstice is as significant as the Spring Festival."
As early as the Zhou Dynasty (c.11th century-256BC), people worshipped the gods on the first day of the Winter Solstice, which also was the first day of the new year. The Winter Solstice became a winter festival during the Han Dynasty (206 BC-220AD). The celebratory activities were officially organized. On this day, both officials and common people would have a rest.
During subsequent dynasties, such as the Tang (618-907), Song (960-1279) and Qing dynasties (1644-1911), the Winter Solstice was a day to offer sacrifices to Heaven and to ancestors.
