烟浊酒清
[yān zhuó jiŭ qīng]
This might mean smoke makes everything turbid while wine remains clear. The idiom expresses contrast - 'Yanzhuo Jiu Qing' refers to the clarity amidst confusion. For instance, when troubles obscure our life view (smoke-like); still, certain virtues or joys remain unaffected and pure, as if undisturbed by worldly matters, especially represented by clear liquor symbolizing true friendship.
