What does "two dragons control water, eleven oxen plow the fields, and nine butchers divide the pigs" mean?

This sentence is the beautiful expectation of the ancient farming era for the bumper harvest of agricultural production in the coming year. In ancient times, agriculture was the foundation. Most of these proverbs are aimed at agriculture and animal husbandry, and they are the wisdom summarized by the ancients to guide agricultural production according to historical phenomena and climate.

Two dragons control the water, eleven Niu Gengdi and nine local pigs. The dragons, cows and pigs here all refer to three of the twelve branches, namely, Chen, Ugliness and Hai. Erlong water control refers to the first day of the lunar calendar, which corresponds to Chenri, and Chenri is a dragon, which also means that this day is for Erlong water control. For example, the first day of the first month in 2020 is the morning, so Er'long River will be governed this year.

The so-called water control means that there will be more rain in the sky. Erlong flood control is to remind farmers to prevent floods and prevent crops from being destroyed by floods, and the harvest of that year was gone. Without modern advanced instruments, the ancients could not detect natural climate and weather changes, and could only rely on the changes of yin and yang and the five elements and the ecliptic of the lunar calendar to infer meteorological changes.

Then, by analogy, it can be calculated that the day when eleven cows plow the fields is the eleventh day of the first month, which is an ugly day and the ugly land is a cow, so this day also represents eleven cows. 1 1 The first cow plows the field. It doesn't mean plowing the field with cows on the eleventh day of the first month, but it means that if this year is the sowing time and many cows are needed to plow the field, it means that the land is very poor and there will be no good harvest this year.

However, some people say that 1 1 plows cattle, that is to say, if there are more plows, that person will not be tired, and farmers can afford to raise eleven cows to plow fields, which means that there is still a lot of money at home, which is a good sign.

Perhaps this is the understanding difference between the north and the south. Proverbs have a lot to do with local culture, so long as they follow the regional culture, they will not cause misunderstanding.

It is a phenomenon that nine butchers kill pigs, which means that nine butchers kill one pig. Nine butchers kill one pig, which also means that pigs are expensive. It also implies that pork prices are high, and pig farmers can continue to raise pigs because it is profitable.
