Reasons for drinking winter wine:

Winter brewing was originally named Dongyang wine, which was named after the rise of Yang after winter.

"Twenty-four solar terms" is a special festival in the calendar, indicating the season, phenology, climate change and the establishment of "December construction". The ancient "Twenty-four solar terms" were determined by the direction of the top of the Beidou bucket handle.

One-year-old is divided into "Twelve Chens" in the official calendar (built in December). "Building" represents the direction of the top of Beidou bucket handle, and bucket handle turns to "Twelve Chens" in turn.

In traditional culture, the time of the main branch is related to the orientation and gossip, and the yin position is the "root position" of the acquired gossip, which represents the end and beginning of the year. Therefore, bucket handle is a cycle from east to north (yin position, the root position of acquired gossip). It began in the beginning of spring and ended in the great cold. When bucket handle points to the "lower" position due north, it is the solstice winter solstice. ?

"leveling method" is a time average method, and the interval of each solar term is about 15 days. The uneven motion of the sun on the ecliptic is not considered in the calculation.
