What is the meaning of Yin River?

The meaning of Yin River: groundwater.

In fact, in the eyes of the older generation, what they call the Yin River is what we now call groundwater. We all know that groundwater resources are very rich, so for thousands of years, it has supported the lives of countless people.

However, the Yinhe River is completely different from the underground river, and it is also a kind of groundwater. Because their location is usually very hidden and not easy to be found, they are called underground rivers. As groundwater, the Milky Way covers all kinds of water resources under the surface, and the scope of underground rivers is much wider.

As groundwater, the Milky Way will be continuously replenished by means of usual rainfall, so so far, the phenomenon of groundwater depletion has not been found.

The role of the galaxy

First of all, the Milky Way, as groundwater, can nourish everything on the earth. All the water lost above the surface permeates below the surface, nourishing all kinds of plants in nature. When these plants thrive, they will interact with water molecules in the air and increase precipitation.

As we all know, what humans need to drink is fresh water, while the water in the ocean is salt water. When the water in the ocean evaporates into the air, the falling rain becomes fresh water. At this time, all kinds of underground rivers will fully absorb this fresh water for people to use. Such repeated circulation will always make the groundwater reserves sufficient.
