素年旧颔首伤年已陌弱
[sù nián jiù hàn shŏu shāng nián yĭ mò ruò]
It's a very poetic way to say 'In simple years, nodding my head with old sorrow makes this year seem so distant and weak'. It reflects on past memories and sorrows, showing that time passing turns people away from those they used to know and creates a sense of nostalgia and sadness for days gone by.
