From an astronomical point of view, the Beginning of Spring symbolizes the arrival of spring, but from a climatological point of view, the Beginning of Spring is just the prelude to spring. The Beginning of Spring in 2017 (23:34 on February 3, 2017 - 19:31 on February 18, 2017)
The Beginning of Spring is not only the first of the twenty-four solar terms in the lunar calendar, but also the beginning of spring. It is classified astronomically, but in nature and in people's minds, spring means the wind is warm and the sun is warm, the birds are singing and the flowers are fragrant; spring also means the growth of all things and farmers sowing seeds.
The ancient book "Qunfangpu" explains the beginning of spring as: "Li means the beginning of construction. The spring air begins to establish." During the beginning of spring, the temperature, sunshine, and rainfall begin to rise and increase. But all this is just a prelude to spring for much of the country.
