挥映在沉默里的渲染挥映在演绎里的悲伤
[huī yìng zài chén mò lĭ de xuàn răn huī yìng zài yăn yì lĭ de bēi shāng]
It’s quite poetic language referring to moments where the quiet atmosphere can make sadness appear deeper - '挥映'(reflection/representation) appearing in both parts emphasizes the influence of silence and the portrayal on melancholic scenes.
