獠牙月伊人憔悴
[liáo yá yuè yī rén qiáo cuì]
This phrase combines a fierce element 'fangs' (usually implying danger or ferocity), and a delicate image of the moonlit woman appearing weary or sad. Perhaps it refers to someone looking tough but vulnerable deep down. Or maybe it is about the beauty under the moon, evoking sympathy and melancholy.
