The Chinese idiom 集思廣益 (jí sī guǎng yì), literally “collective wisdom reaps wide benefits,” states that gathering opinions while drawing on all useful ideas is of broad benefit to all.
The idiom originated from a story about the strategist and statesman Zhuge Liang in the historical text “Records of the Three Kingdoms,” which covers the history of China’s late Eastern Han Dynasty (A.D. 184–220) and Three Kingdoms Period (A.D. 220–280).
