4. Cultural Background and Notes

• The phrase is related to an expression in the Book of Songs (诗经), specifically in the 'Greater Odes' (大雅) section: 'The workings of Heaven have neither sound nor smell' (上天之载，无声无臭). While the original context referred to the invisible but certain influence of divine providence, the modern idiom 无声无息 (wú shēng wú xī) focuses more on literal silence or social obscurity.
• Depending on the context, the idiom can carry different nuances. It can be neutral (describing a quiet night), positive (describing a humble, quiet contributor), or negative (describing a failure that no one cared about or a lonely passing).
