Winter is coming to an end. Will it be cold after beginning of spring?

It's still very cold after beginning of spring. The beginning of spring solar terms in westerly jet, the southern branch of East Asia, have begun to weaken, and the winter climate is coming to an end. However, the strength and location of the northern branch westerly jet remain basically unchanged, and the Mongolian cold high and Aleutian low are still relatively strong.

Beginning of spring is the first of the 24 solar terms. Standing means "start"; Spring represents warmth and growth. Twenty-four solar terms were originally formulated according to "variable stars". When the bucket handle of the Big Dipper points to the cloudy, it is beginning of spring.

At present, solar terms are determined according to the longitude of the sun. When the sun reaches longitude 3 15, it will be the beginning of spring, and the festival will be held from February 3 to 5 of the Gregorian calendar every year.

Agricultural activities:

Beginning of spring is one of the "four stops". In ancient times, "Sili" refers to the beginning of spring, summer, autumn and winter, and its agricultural significance is "spring planting, summer sowing, autumn harvest and winter storage".

The 24 solar terms play an extremely important role in the traditional farming society in China. The twenty-four solar terms are related to cadres and gossip and have a long history.

The ancients began to explore the mysteries of the universe very early, and thus deduced a complete and profound star-watching culture. In ancient times, people set up astronomical phenomena, observed phenomena and timed them, and created gossip and calendars, thus civilization began. Twenty-four solar terms are the product of ancient farming civilization, which contains the long-standing cultural connotation and historical accumulation of the Chinese nation.
