少年妳已不再年少少女妳已不再幼稚
[shăo nián năi yĭ bù zài nián shăo shăo nǚ năi yĭ bù zài yòu zhì]
'Boy, you’re no longer young; Girl, you’re no longer naive'. This acknowledges that both males and females have undergone growth and maturity. They are older now with experiences behind them, leaving the innocence and naivety associated with youth further in the past.
