绾青白发
[wăn qīng bái fā]
It translates as 'Coiling up the darkened white hair,' signifying a graceful acceptance of aging, where 'qing' (青) is sometimes used poetically for a color between green and blue, also indicating black when it comes to Chinese classical poetry about oldness or melancholy, hence giving an elegant image of someone who has aged beautifully while still holding their own dignity and charm.
