Pinyin in spring
Spring blossoms, an idiom in China, the pinyin is ch ū n nu m 4 n hu ā k ā i, which means beautiful spring. Now it is often used to describe a good situation conducive to work or study. From: Zhu Ming Guozhen's "Zhuang Yong's Sketch Nannei": Spring blossoms, and you have a banquet with the cabinet Confucianism.
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.
climate
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.
Many animals are in estrus during this period, so China also calls spring the season when everything recovers. Because hot air began to move northward, while cold air often lingered, in addition, the temperatures of land, water and air all rose at different speeds. From the meteorological point of view, China belongs to the monsoon climate zone, and spring is the period of alternating winter and summer monsoon, so the cold air and warm and humid air flow are changing, and they do not give in to each other.
