Four words about spring

Four words about spring: Yanwu, Ying Ge, bloom, the earth, and bloom.

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 October is designated as spring.

Climatic characteristics

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 of "the revival of everything".

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. In the southern region, a cold air intrudes every three to five days in spring, and meets with the southwest warm and humid airflow, forming rainy weather.
