How long should I wear a cotton-padded jacket after beginning of spring?

The warming time in different regions is different, almost in May in the north and around March in the south.

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 on the basis of "variable stars". When the bucket handle of the Big Dipper points to the shade, 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. In the era of cadres and branches, silver moon is spring, beginning of spring is the first year, and beginning of spring is the beginning of all things, which means that all things are self-renewing, which means that a new cycle has begun. In the traditional concept, beginning of spring has auspicious meaning.

Beginning of spring marks the end of the winter when everything is hidden and begins to enter the warm and sunny spring. In nature, the most striking feature of beginning of spring is that everything is beginning to show signs of recovery. As far as beginning of spring is concerned, you can obviously feel the breath of early spring in the Tropic of Cancer (Huangchi Jiao Jiao) and its south. Due to China's vast territory, large span between north and south, and different natural rhythms, the "beginning of spring" in many areas is only a prelude to spring, and everything has not yet recovered, and it is still in the winter when everything is hidden.
