Does beginning of winter represent late autumn or early winter?

Beginning of winter is the representative of early winter, and beginning of winter is the beginning of winter. During my stay in beginning of winter, it is necessary to supplement food customs to survive the severe winter.

Beginning of winter solar terms and high-altitude westerly jet have been fully established in South Asia. At this time, the fluctuation of the south branch of the high-altitude westerly wind and its eastward movement have great influence on the precipitation weather in Jianghuai area. When the zonal circulation in Asia and the fluctuation of the south branch of the westerly wind are strong, there will be a wide range of rainy weather. In addition, the zonal circulation will end, the meridional circulation will be established, and there will be a cold wave and significant cooling.

Before and after winter, precipitation in most parts of China decreased significantly. The land in the northern region freezes, and agricultural and forestry crops enter the wintering period; The "Sanqiu" in Jianghuai area is drawing to a close, and Jiangnan is scrambling to plant late-season winter wheat and quickly transplant rapeseed; The south is the best time to grow wheat.

Understanding "beginning of winter" can't just stay in the sense of beginning of winter. Tracing back to the source, the ancient people's understanding of "establishment" is the same as that of modern people, both of which mean establishment and beginning. However, the word "winter" is not so simple. "Winter, in the final analysis, is also a collection of all things", which means that all the crops in autumn are harvested and put into storage, and all the animals are hiding and hibernating.
