 For centuries, the Yijing’s commentators heeded the Xugua authors’ advice to read Ge and Ding together as two phases of a regime change (see WB: 635, 641). While Ge discusses the destructive phase of toppling an old regime, Ding refers to the constructive phase of rebuilding the political order. The two hexagrams jointly call attention to the danger of political corruption, the fear of a tyrant, and the anxiety of losing control amid political upheaval. More important, the two hexagrams highlight the importance of making the right decision amidst power struggles. For this reason, through the centuries, Ge and Ding received special attention from commentators who were interested in political philosophy (see, for instance, Wang Bi’s commentary in Lynn 1994: 444–59).
