How many flowers can spring change?

A change in the word "spring" can produce thousands of flowers, because it is like a strong wind in spring, which blows at night and blows away the petals of 10 thousand pear trees.

Spring, the first of the four seasons, refers to the period from beginning of spring to 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. 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.

Brief introduction of seasons

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 process of cultural exchange and communication in historical development, there are four solar terms (vernal equinox, autumnal equinox, summer solstice and winter solstice) reflecting the return of the direct point of the sun.

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 in the "vernal equinox" 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.
