If the farming era disappears, will the 24 solar terms still have great significance?

Introduction to Ertao: Twenty-four solar terms are the crystallization of the wisdom of ancient Chinese people and reflect the laws of nature. Each solar term has its special meaning, representing the change of seasons. It is not only related to our farming culture, but also closely related to our lives, telling people their living conditions and changes.

Beginning of spring, vernal equinox, long summer, summer solstice, beginning of autumn, autumnal equinox, beginning of winter and winter solstice are eight solar terms.

Beginning of spring, Changchun, beginning of autumn and beginning of winter tell us the beginning of the four seasons. The weather gradually changes to the next season. For beginning of spring, beginning of spring's solar term is "when the world thunders, everything breeds", which is to remind people that spring is the season of hair growth, and when animals and plants are in the process of hair growth and prosperity, spring should not be harmed at this time. At this time, the weather is getting warmer and warmer, and everything wakes up from the ground. At this moment, with the change of honesty, it is easy for people to catch a cold and get sick, so we have to pay attention to it.

The vernal equinox, autumnal equinox, summer solstice and winter solstice are divided from an astronomical point of view, reflecting the turning point of solar height change. What does the vernal equinox mean? It means equal share, and the vernal equinox means equal share between day and night.

There are five solar terms symbolizing temperature change: slight summer heat, great summer heat, summer heat, slight cold and severe cold;

Reflecting precipitation are: rain, Grain Rain, Bailu, cold dew, first frost, light snow and heavy snow;

The three solar terms, White Dew, Cold Dew and First Frost, on the surface reflect the phenomenon of water vapor condensation, but in essence they reflect the process and degree of gradual temperature drop.

The solar terms reflecting phenological phenomena or agricultural activities are: fright, Qingming, Xiaoman and Mang. Frightening and Qingming reflect natural phenological phenomena, especially stinging, which indicates that spring will return with the recovery of early thunder in the sky and underground stinging insects.

"Li" is the beginning of all seasons, and four "Li" in spring, summer, autumn and winter are the beginning of four solar terms. Beginning of spring, Changsha, beginning of autumn and beginning of winter are also called "four seasons". "Li Si" indicates the beginning of the astronomical season. As far as climate is concerned, it is still in the last season. For example, the Yellow River Basin in early spring is still in the middle of winter.

"Zhi" means extreme and most. The summer solstice and the winter solstice are collectively called the "second solstice", indicating the extremes of summer and winter. . The summer solstice is the longest day in the northern hemisphere. Winter solstice is the shortest day in the northern hemisphere. Tell us the changing law during the day, and we need to adjust our sleep habits, just like we all go to bed early in winter. That's the truth.

"Points" here means equal distribution. The vernal equinox and autumnal equinox are called "equal share", which means that the length of day and night is equal. These two solar terms, the sun shines directly on the equator, and day and night are equal.

It's not that with the development of science and technology, the use of solar terms in agriculture is not so important, but the solar terms summed up by the wisdom of China ancients, which are not only related to our farming culture, but also integrated into our lives all the time. Summarize twenty-four poems for everyone: Spring rains shake the spring and clear the valley, and summer is full and summer is full; Autumn dew, autumn frost, little snow in winter and cold in winter. The first half of the year is June 2 1 day, and the second half is August 23. The dates of the two festivals are fixed every month, with a maximum difference of one or two days. "
