A时间都去哪了
[a shí jiān dōu qù nă le]
It translates to 'Where did the time go?' The preceding letter A doesn't seem particularly necessary but could be intended as style or just part of the unique expression chosen by the individual; generally reflecting nostalgia or regret over passed time and wonder at where that time disappeared to, questioning the passage of life quickly and subtly expressing some lamentation over lost moments.
