The world is so big that it is impossible to stay clean all the time. There are always some filthy things that will appear, maybe haphazardly, maybe one after another, but no matter which kind they are, they will eventually appear. So, if this filthy thing is around you, will you choose to turn a blind eye and deliberately avoid it to avoid harming yourself; or will you face it directly, no matter how dirty it is, just treat it as a test? Which one do you choose?
