What does it mean to control water in Kowloon? Is there more water or less water?

Huang Li used "Jiulong Water Control" to predict the rain in the coming years. The reason is that many dragons manage water, but as a result, there is no dragon cloud to manage rain. 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 Yellow 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.
