这首诗由唐朝诗人谭用之所作,谭用之生活在晚唐时期,社会动荡,个人境遇多舛。诗中描写秋夜与友人话旧的情景, likely reflects the author's personal experiences of nostalgia and friendship during a time of political instability and personal reflection. The autumn setting symbolizes transition and melancholy, while the dialogue with an old friend highlights the comfort of shared memories in uncertain times.
