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. It also means that this day is for Erlong water control. For example, this year, 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 it will rain more in the sky. Erlong flood control is to remind farmers of flood control and prevent crops from being washed away by floods, and the harvest achievements of that year are 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, and the ugly land is cows, so this day also represents eleven cows. Farming with 1 1 head of cattle does not mean plowing with cattle 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 land, it means that the land is very poor and there will be no good harvest this year.

However, some people say that 1 1 plowing cattle means that if there are more Niu Gengdi, that person will not be tired, and farmers can afford eleven Niu Gengdi, which means there is still a lot of money at home, which is a good sign.

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

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