What does it mean that four people are divided into three in the old yellow calendar?

For thousands of years, China's national calendar dates have been sorted by 60 Jiazi, namely: A, B, C, D, E, Ji, G, Xin, Ren, Gui "Ten Days Dry" and Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Shu and Hai "Twelve" (1), counting dragons to control water: From the first day of the first month, look at the day when "Morning Day" is located. The first day of the first month is Chenri, which is called "Yilong Water Control", and the first day is the tenth day of the first month, which is called "Ten Dragons Water Control"; (2) How many cows plow the field: If the third day is ugly, it is called "three cows plow the field"; If the ugly day is the seventh day, it is called "seven cows plowing the field"; (3) A few days of excitement: If the first day is an "exciting day", it is called an "exciting day". If the ninth day is "Xin Ri", it is "Xin on the ninth day"; (4) How many people divide C: If the fifth day of junior high school is "C Day", it is called "five people divide C". If the eighth day is "the third day", then "eight people share it equally".

So what are the actual meanings of these four nouns?

"Counting dragons to control water": "Many dragons depend on it, few dragons drown it", "Many dragons don't control water". It means that the fewer dragons, the more water; The more dragons, the less water. "Yilong water control" is good, and the grain is abundant; The "Twelve Dragons Control Water" is either drought in most areas, or flooding in some areas and crop failure.

"A few cows plow the field": "Cow" stands for "productivity". The more cattle are plowed, the better, and the productivity is abundant, which is not only conducive to large-scale production, but also conducive to intensive cultivation and good harvest. For example, "one cow plows the field", which is seriously lacking in productivity and will affect farming and harvest.

"After a few days, I will be excited": In "The sky is dry and things are dry", the five elements of "excitement" belong to "gold", and "excitement" means "gold". The more days you get gold, the better, just as making a fortune every day is a businessman's long-cherished wish and great pleasure. However, there is also a saying that "getting gold in one day" means getting money earlier in the year, and "getting gold on the twelfth day" indicates that it was developed later this year.

"How many people divide C": Because of the homonym of "C" and "cake", "How many people divide C" is also called "How many people divide cake". Every year, the fruits of labor are certain, and the fewer people you share, the better. If one person is full and ten people share it, everyone will be hungry.
