别了那些年迷惘的青春
[bié le nèi xiē nián mí wăng de qīng chūn]
It means 'Farewell those perplexed years of youth'. It captures a reflective moment where the speaker bids goodbye to times of confused adolescence full of uncertainty and searching. There’s an aspect of maturity achieved now which understands better and has resolved some questions of identity that once troubled them. Also hints at the nostalgia associated with remembering formative yet bewildering periods of youthfulness
