Three ancient poems about spring
Spring is one of the four seasons, between beginning of spring and Long Summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain. Spring represents warmth and growth. In spring, the qi of yin and yang begins to change, and everything germinates and grows with the rise of yang. Spring is a period of alternating winter and summer monsoon, with cold air and warm and humid air alternating.
As far as solar terms are concerned, spring in China begins in the beginning of spring (February 2-5) and ends in the long summer (May 5-7). In Europe and America, spring begins at the vernal equinox in China and ends at the summer solstice. In Ireland, February to April is designated as spring.
At present, the method of "waiting for average temperature" proposed by modern scholar Zhang Baokun is often used to divide the four seasons in China. Taking the five-day average temperature as the standard, the five-day average temperature after winter passes 10℃ and begins to enter spring. When the temperature is higher than 22℃, it means the end of spring and the beginning of summer.
Explain the word "spring" by explaining the text, which is a verb and means "push". From the grass to the sun, the grass was born in spring, which means that the grass feels the call of the sun, acts in time, pushes the earth away and grows. "Biography of Shangshu" said: "When spring comes, everything comes out." The original meaning of standing is that people stand on the earth.
Spring is one of the four seasons. As far as solar terms are concerned, spring begins in early spring and ends in long summer. Twenty-four solar terms are the product of ancient farming civilization in China, and the division of four seasons begins with "four stands".
In the historical development, cultural exchange and communication, four solar terms (vernal equinox, autumnal equinox, summer solstice, winter solstice) reflecting the return movement of the direct point of the sun were all over the pre-Qin period. The division of the four seasons in the west is based on the dichotomy, that is, spring is divided into beginning of spring.
The vernal equinox from bisection to Mid-Autumn Festival is also the New Year of Uzbekistan, Turkey, Afghanistan, Iran and other countries, with a history of more than 3,000 years. In Ireland, February to April is designated as spring.
In spring, the northern hemisphere of the earth began to tilt towards the sun, receiving more and more direct sunlight, so the temperature began to rise. In spring, plants begin to sprout and grow, and many flowers bloom. Hibernating animals wake up, many animals with eggs for the winter hatch, and birds begin to migrate, leaving the wintering ground for breeding grounds.
