倾国倾城何不倾其所爱
[qīng guó qīng chéng hé bù qīng qí suŏ ài]
This username implies a beauty capable of bringing down nations but expresses that the real charm should be focused on someone one loves. '倾国倾城' is a Chinese phrase meaning ‘so beautiful that it can cause kingdoms to fall', and '何不倾其所爱' means ‘why not devote oneself wholly to love’.
