一去不复返 Gone ; I keep hunting my sweet heart ; be dead and buried

光阴一去不复返 Time flies never to be recalled ; Time lost can not be recalled ; Lost time is never found again ; all time is no time when it is past

悲伤一去不复返 my sadness is gone

时间一去不复返 Automatic Calendar Shredder ; Time Never Goes Back ; Time gone ; Return

过去的将一去不复返 Past is gone forever ; Past gone forever

时光一去不复返 Time gone ; Time is gone forever

光明一去不复返 Bright gone forever ; The light never to returns ; Light gone

从此一去不复返 And it never comes again

勇士一去兮不复返 go all the way

将一去不复返 humped shaped curve
