The origin of solar terms

China's astrology culture has a long history and is profound. The ancients began to explore the mysteries of the universe very early, and thus deduced a complete and profound star-watching culture. Twenty-four solar terms were originally formulated according to the bucket handle rotation direction of the Big Dipper, which rotates circularly and is closely related to the seasonal changes. The Big Dipper consists of seven stars, namely Shu Tian, Tian Xuan, Tianji, Tianquan, Yuheng, Kaiyang and Yaoguang. Named for its twists and turns.
