Twenty-four solar terms were originally determined by 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.

The Big Dipper is an important astrology in the northern hemisphere (China is located in the northern hemisphere). The climate and phenology of Huangchi Jiao Jiao and its vicinity in the northern hemisphere also changed gradually when the stars were running, which became the basis for ancient people to judge the change of solar terms, that is, the so-called "bucket handle refers to the east, and the world is spring; Guide to barrel handle, it's summer in the world; Bucket handle refers to the west, and the world is autumn; Bucket handle refers to the north, and the world is winter. ".

In ancient culture, the time and position of branch and gossip are linked together. Yin position is the root position of the acquired gossip, the position at the end of the year and the beginning of the year, representing the end and beginning. For example, "Yi Shuo Gua Zhuan": "Gen, the divination in the northeast is also the beginning of all things."

That is, bucket handle starts from due east to north (yin position, gossip position the day after tomorrow) and makes a circle around east, south, west and north as a cycle, indicating one of the "years" (from beginning of spring to the next beginning of spring is one year old). Silver moon said that "spring is positive", and the beginning of spring is the beginning of a year. Bucket handle, the Big Dipper, points to the establishment of the 24 solar terms, starting from beginning of spring and ending in severe cold.
