Who knows what a few dragons control water and a few cows plow fields?

It is determined according to the date of the first day of the first month of each year. For example, the fifth day of the first month is called "Five Dragons in Charge of Water", and the sixth day is called "Six Dragons in Charge of Water", and so on. It is said that the more dragons, the less rainfall, and the less dragons, the more rainfall. Since ancient times, there has been a folk proverb that "there are many people and it doesn't rain".

A few cows are ploughing the land.

The first ugly day every year (ugly day for cows) is on the first day of the first month, that is, "several cows plow the fields." The more cattle, the better. The more, the better.
