How to read seasonal English?
Four seasons refer to four seasons that appear alternately in a year, namely spring, summer, autumn and winter, and each season lasts for three months. All the year round is formed because the earth revolves around the sun. Due to the existence of the ecliptic angle, the direct point of the sun moves back and forth between the north and south latitudes of the earth, which leads to the change of the height of the sun at noon and the length of day and night, thus resulting in seasonal changes.
The commonly used methods of season division mainly include "solar terms method" and "temperature method". Traditionally, China begins with four solar terms (beginning of spring, Changchun, beginning of autumn and beginning of winter).
Zhang Baokun, a modern scholar, put forward a new standard for the division of seasons. The average temperature (the average temperature for five consecutive days) is beginning of winter, and when it rises above 22℃, it is long summer. The average temperature in spring or autumn is 10-22℃.
spring
The four seasons appear alternately in a year, and the change of the four seasons is a continuous process. It is also a process of yin-yang transformation, from one side to the other, quantitative change produces qualitative change. In this gradual process, beginning of spring, Changxia, beginning of autumn and beginning of winter, also known as "Sili", are the beginning of the season.
Spring ranks first among the four seasons, and a new cycle begins. 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 the season for all things to grow and sow. The so-called "one year's plan lies in spring".
