From 《史记·平原君列传》: Zhao retainer 毛遂 persuades the king of Chu to send troops, after which Lord Pingyuan says Mao Sui's tongue 'is mightier than a million soldiers' and his single visit to Chu made Zhao 'heavier than the nine tripods' (九鼎 were the sacred bronze vessels symbolizing dynastic legitimacy).
