The classic sayings about water are:

1. If humans do not save water, the last drop of water on the earth will be our own tears.

2. When you let the water drain away in vain, we are one step closer to drought.

3. Running water is the endless blood of nature. Destroying water sources is equal to polluting your own blood!

4. If the soil is wet, the vegetation will not grow; if the water is wet, the fish and turtles will not grow.

5. If you want to catch fish, you must first clear the water; if you want to catch birds, you must first make trees.
