Water is the source of life, please save water.
Fresh water is decreasing, so it is not good to waste. If you don't save it, the consequences will be great.
Saving water is glorious, but wasting water is shameful.
Save every drop of water and benefit all mankind.
Cherish every drop of water and have a beautiful tomorrow.
The pillars of the country are indispensable, and the water of life cannot dry up.
