I came across this warning in a public restroom within the International Airport at a city in the province of Shantou, China. For the life of me I can not tell what this means. If by saving my own bum I can do the environment some good, by all means sign me up. And by the way, I love these awkward signs around China so whoever is going around correcting them, please stop. Its all part of the romance of living in a foriegn country. The imperfections are cute and adorable, like Mona Lisa's smile.
