The year 2020 is "Two Dragons Harnessing Water". Eleven cows plow the fields, and ten people divide the bread. "

Two dragons control the water, eleven oxen plow the fields, and ten people share the bread. This is an ancient algorithm. This algorithm is calculated from the first day of the new year in 2020, which is what we usually call the first day of the first month. Look at the days of the year when Chou Shi and Chou Shi appear. And it means that on the second day of 2020, the morning will appear, that is, Erlong will control the water. On the eleventh day of the first month of 2020, it was an ugly day, so eleven cows plowed the fields. At the same time, the tenth day of the first month in 2020 is the third day, so ten people divide the cake. This algorithm is an ancient algorithm, but now many people in rural areas still know this algorithm.

This is the result of farmers reading old calendars. In ancient times, farmers depended on the weather, so they would use an algorithm to calculate the weather in the coming year. In 2020, there will be two dragons to control the water, eleven cows to plow the fields and ten people to share the cakes, which indicates that the weather of farmers will be better in 2020 and farmers will be in a state of bumper harvest this year. In other words, there will be enough precipitation next year, so farmers don't have to worry about the drought of crops, so there will be a bumper harvest. Niu Geng told us that if you plant a lot of crops next year, the harvest may not be very good, so you should plant less crops next year. Ten people sharing the cake is telling us that although there will be plenty of precipitation next year, the farmers' harvest will not be very good.

In fact, this sentence is also the crystallization of the wisdom of ancient farmers. In ancient times, they would choose a method to predict the weather next year. This algorithm is what we are talking about now. Through this sentence, we can predict the farmers' harvest next year.

This sentence is a very old algorithm, and it also means to tell us in advance what the farmers' harvest will be like next year.
