What are the four words of spring?

The four words of spring are: warm spring in bloom, all loves, the grass grows and the warblers fly, the willow blossoms are bright, the birds are singing and the flowers are fragrant, the spring is full, the spring returns to the earth, the spring is sultry, the spring is dim, the apricot rains and pear clouds, the birds are singing and dancing, the flowers are red, the flowers are green, the spring hills are laughing, the spring water is leaking, the oranges are red and the wine is drunk.

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. Late spring is in long summer (between May 5th and 7th). 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.
