Jiulong flood control and drought relief

Huang Li used "Jiulong Water Control" to predict the rain in the coming years. Originally, it was said that many dragon pipes were used to control water, but as a result, there was no distribution of dragon pipes.

There are five dragons to control water, two dragons to control water and so on.

Now it means more: one thing is managed by many people or departments, and as a result, one person has one opinion, and no one can manage it well.

There are also some sayings in the Gregorian calendar, such as Niu Gengdi, killing pigs, silkworm bathing, etc., which are all predictions of agricultural production. It reflects the agricultural civilization and farming culture of China for thousands of years.
