深海屿鹿

This translates as 'Deer Island in the Deep Sea'. Such a combination of elements can express isolation (an island far from land, representing solitude), depth (a reference not only to physical oceanic depth but potentially metaphorical depth such as emotions), and a touch of beauty or innocence (represented by the deer). This netizen name could be a reflection of a wish to be peaceful, secluded, while holding onto an innocent part inside oneself.
