Sign, sign everywhere a sign. Do this, Don't do that. Why don't you read the sign?

This falls under the general category of mundane daily life on a mission station.  I have noticed these flyers posted on or near the garbage bins around the station.  Our maintenance crew is responsible for collecting the trash, so I suspect someone from Maintenance posted them.

Read my translation first, then go back and study the photo:

"Notice:  Please do not put dirt or plant material in the rubbish bins.  Only put plastic or metal (in the bin).  Whatever material you can make into compost in your garden, do not put in the rubbish bin.  Please pay attention to this notice.  If you continue to put these things in the bins, you will pay a penalty.  Inform everyone in your house."
