Bathroom Signage

     Bathrooms in Shanghai are always an adventure.  We've learned to enter cautiously, pay careful attention to signs and to not get our hopes up.  We've been in some nice bathrooms.  I'd even say some were cool based on the decor. Then we've been in some bathrooms that were unspeakable.  Today I found myself in the women's bathroom at one point for a few seconds until a realized the sign was just above the door knob.  I'm not going to get into poopy talk but Friday night I saw a sign above a urinal that I need help interpreting.  After school I went to a pool hall down the road with some other teachers and saw this in the restroom (which by the way I've found that only Americans call them restrooms).  I'll get back to you all if I can find out what advice this sign has to offer.  Take special note of the pictures at the bottom which I zoomed in on below.  It might be blurry.
