The origin of solar terms in beginning of winter and the introduction of solar terms in beginning of winter

1, "Twenty-four solar terms" says: "Immediately is the beginning", and it also says: "Winter is the end, and everything is harvested." It means that the crops in autumn are harvested and put into storage, and the animals are hiding and hibernating. It seems that the beginning of winter does not just mean the coming of winter. In a word, beginning of winter means that when winter begins, everything will be collected to keep out the cold.

2. beginning of winter and beginning of autumn are the same. The ancients also used divination to see the warmth and coldness of winter in this season, such as "it's sunny in beginning of winter, and it's cold in one winter"; Early winter is cloudy (rainy), and one winter is warm (warm winter). There are no exceptions. In ancient times, on the day of beginning of winter, the emperor personally led the doctors of three public officials to the northern suburbs to welcome the winter.

3. In ancient China, beginning of winter was divided into three stages: "When the water is still, the ice begins; The second waiting place began to freeze; Three times, people are drowning. " This solar water can already form ice; The land also began to freeze; In the third stage, pheasant refers to a big bird like pheasant, and pheasant is a big clam. After beginning of winter, big birds like pheasants are rare, but you can see big clams with similar lines and colors at the seaside. Therefore, the ancients thought that pheasants would become big clams in early winter.

4. In beginning of winter season, the sun has reached the longitude of 225, and the solar radiation in the northern hemisphere is getting less and less, because there is still a certain surplus of heat stored on the surface in summer and half a year, so it is generally not too cold. When there is no wind on a sunny day, there is always warm and comfortable "Xiaoyangchun" weather, which is not only very pleasant, but also very beneficial to the growth of winter crops. But at this time, the cold air in the north also has a strong force, often invading the south frequently, and sometimes it will form a cold wave weather with strong winds, cooling rain and snow.

5. China's solar terms are the carrier of farming customs, and history has passed, leaving behind culture. Festival customs are actually agricultural customs and culture (food customs are also one of them). Although it has no practical significance in modern life, it adds interest to life. Beginning of winter, together with beginning of spring, Changxia and beginning of autumn, is called "Four Seasons", which is an important festival in ancient society. On this day, the emperor will lead civil and military officials to the northern suburbs of Beijing to set up an altar for sacrifice. Now, when people enter the early winter, they should also celebrate. Beginning of winter's food supplements vary from place to place. Most northerners want to eat jiaozi in early winter, but in southern China, people like to eat chicken, duck, fish and so on in early winter.
