往事余声彼时此景
[wăng shì yú shēng bĭ shí cĭ jĭng]
'Echoes of the past, scenes of that time'. This is a poetic way of expressing nostalgia, recalling old memories and emotions associated with them. 'Yu Sheng' implies the lingering afterthought or sound which symbolizes the deep influence of those past scenarios in heart.
