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

复返迁移 recurrent migration ; return migration

悲伤一去不复返 my sadness is gone

去而复返 There and Back Again ; Partir Revenir

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

永不复返 Nevermore ; Never Moa ; nevermoa

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
