What are the background pictures of 24 solar terms in the Winter Olympics?

There are 24 solar terms in the design of the opening ceremony of the Beijing Winter Olympics, because the first "beginning of spring" is in the solar term on February 4th, and the director just discovered the particularity of that day, thus pulling away the opening ceremony of the Winter Olympics. "Twenty-four solar terms" is known as the fifth invention in China, which contains profound cultural connotations, among which "Twenty-four solar terms" respectively correspond to 24 beautiful ancient poems of China. Beginning of spring insists on welcoming the New Year, and uses characters as the opening design of the Winter Olympics, which also means that Beijing welcomes friends from all over the world to participate in the Winter Olympics.

Twenty-four solar terms began in the beginning of spring and ended in great cold. Formally, we can clearly divide 12 months in China into specific festivals. Originally defined according to the star shift, each revolution is a period, in which every 15 degree is equally divided, which is also a solar term. Now, the "24 solar terms" are determined according to the position of the sun's return to the ecliptic, and the annual movement track of the sun is divided into 24 equal parts, and each equal part is divided into a solar term. The "twenty-four solar terms" thus divided have played an important role in agricultural production in China since ancient times and have far-reaching influence.

The twenty-four solar terms reflect three obvious characteristics: season, phenology and climate change. Among them, beginning of spring, summer solstice, beginning of autumn, beginning of winter, vernal equinox, long summer and autumn equinox are eight solar terms. Beginning of spring, Changxia, beginning of autumn and beginning of winter have become "four stands". Every day when these solar terms begin, the four seasons begin. "Twenty-four solar terms" can also reflect the changes of paragraphs, such as the five solar terms of slight summer heat, great summer heat, summer heat, slight cold and great cold. The other seven solar terms can reflect weather scenarios and phenological phenomena. It has played an important role in China ancient farmers' farming and cold and warm changes.

The above is the specific origin of China's invention of "Twenty-four solar terms". In every solar term, China will have traditional customs and activities, such as eating jiaozi and noodles in the diet, which represents a form of inheriting culture and pinning thoughts among the people, so many entertainments, health preservation and etiquette are introduced. It is very important to know what to do and what not to do in solar terms.
