被风吹乱的回忆被雨淋湿的笑颜
[bèi fēng chuī luàn de huí yì bèi yŭ lín shī de xiào yán]
Translated as 'memories messed up by the wind, smiling face wet by the rain'. The user likely wants to convey nostalgic yet sorrowful moods mixed with past joyous memories, probably referring to the influence emotions can exert upon us, much like nature’s impact.
