往事如风你便是风
[wăng shì rú fēng nĭ biàn shì fēng]
'Wang Shi Ru Feng Ni Bian Shi Feng', meaning that 'The past is like the wind, and you are the wind'. It depicts that something (or someone, which could be the interlocutor) from the past, like winds blowing away without leaving a trace but meanwhile signifies that person's presence was as natural yet influential as wind.
