Reversal at Extremes: Decline After Peak Is the Law of the Universe
Fan Li deeply believed that when things reach their extreme, they inevitably reverse. If one does not retire when fame and achievement peak, disaster will follow. If wealth accumulated to the extreme is not dispersed, envy and calamity will come. This philosophy, rooted in Daoist thought, was the underlying logic of all his decisions.
