cleaner and clean
The relationship between the cleaner and clean.
It seems that the clean can't get all the benefit from the cleaner as the cleaner get from the clean
可能是“cleaner get from the clean”= cleaner get all the benefits from the clean
cleaner（清洁工人？）不够尽职尽责，他从clean的工作中获益却没有很好的完成clean这个工作。
I'm not sure...open to discuss...
