纵然风情万种无风无雨无晴
[zòng rán fēng qíng wàn zhŏng wú fēng wú yŭ wú qíng]
It’s derived from ancient poetry. Loosely speaking, it implies even with thousands of allures there may still be days without joy (no wind nor sun or cloud). This suggests an indifference despite countless attractions around, or feeling numb regardless many enticements in life.
