How can I interpret 不要为你的美丽伤了我? A sign near some grass says:

不要为你的美丽伤了我

And an English translation says:

Don't hurt me for your pretty


That's pretty close to what google translate says — and I can't see any reason to dispute it. But I can't make sense of the sentence. (I might guess from the context it's something like &quot;don't step on the lawn&quot; or &quot;no littering or vandalism&quot; or something like that. So what on earth could it mean?
This is quite typical of language in mainland-Chinese public service announcement type signs, which tend to be quite &quot;cutesy&quot; in tone. Stuff like personifying inanimate objects (such as flowers) and writing it from the object's point of view fits with this tone.
The literal meaning is:

don't hurt me for [the sake of] your beauty

Which I suppose is hinting that the reason you might trample the grass is to take an attractive selfie/photo.
Edit: From the photo you attached, it's more likely referring to the flowers than the grass (in other words, don't harm the flowers by picking them).
