青丝白烟
[qīng sī bái yān]
It translates literally to 'greenish-black hair and white mist'. This can either refer to an image of beautiful dark hair against a backdrop of hazy mist (perhaps alluding to poetry or romance); or metaphorically signify a phase of youthfulness contrasted with fleeting time and memories, hinting at contemplation over life's transitions and reflections of age-old imagery from Chinese literature about beauty, melancholy, impermanence etc.
