Okay, the user wants me to translate "litter bin" into Simplified Chinese. Let me think. First, "litter bin" is a trash can or a bin for disposing of litter. In Chinese, the common term is "垃圾桶". Let me confirm if there's any other term, but I think "垃圾桶" is the standard one. Since the user specified Simplified Chinese, I don't need to change anything else. Just output "垃圾桶" directly without any explanation. Alright, that should be it.
