妃子笑公子懵
[fēi zi xiào gōng zi mĕng]
'Feizi Xiaogongzi Meng' implies a romantic context from traditional Chinese culture where 'Feizi' represents a favored concubine smiling and being carefree while 'gongzi meng' (bemused young master) might express a young man being lost and confused. It seems like it expresses complicated love relationships between two people at different social levels. In the context of online aliases, this might suggest someone whimsical or interested in historical romance.
