Sima Qian (c. 145-86 BC), the Herodotus of China, testifies as to the potential for a joke or a clever turn of phrase to unravel knotty problems. This is from his biographies of jesters, the first and perhaps foremost source of classical Chinese references to jesters and their role.
‘Even a joke or a witty turn of phrase can do a good job in solving some of the world’s knotty problems and tricky situations.’
