The origin of beginning of autumn

On August 7th or 8th every year, beginning of autumn is considered as the time when the sun reaches 135. Beginning of autumn's "stand" means the beginning, and "autumn" refers to the maturity of crops. Beginning of autumn means that summer will cool down and autumn will begin. This is a solar term that reflects the season.

According to "Twenty-four solar terms": "Autumn is also contending, and things gather here". Beginning of autumn not only indicates that hot summer is coming, but also autumn is coming. It also means that the vegetation begins to bear fruit and children, and the harvest season is here. At this time, early rice harvesting and late rice transplanting in Central China, autumn crops entered an important growth and development period. The ancients regarded beginning of autumn as an important moment at the turn of summer and autumn, and always attached great importance to this solar term.

On the day of beginning of autumn in ancient times, the emperor would lead officials of civil and military forces to the western suburbs to offer sacrifices to welcome autumn, and ordered military commanders to start training soldiers to defend the country. In addition, both the imperial court and the people will choose the auspicious day after the autumn harvest. On the one hand, they will pay homage to God and ancestors, and on the other hand, they will try the newly harvested rice valley to celebrate.
