Happy and convenient, easy to wash.

Suddenly, clean and relaxed.

Slogan for saving water in toilets: wash when you come, close when you leave, and save water resources around you.

Cherish water, cherish water and save water from me!

Fingertips are dripping, and water is stored in your heart.

A drop of water is a drop of tears, please don't let it flow away in vain.

Official website, a master of wall charts, has a series of slogans about toilet culture. You can go there and choose one. You can search for "wall culture" on Baidu.
