The Chinese character for this hexagram means in its original sense an animal's pelt, which is changed in the course of the year by molting. From this word is carried over to apply to the "moltings" in political life, the great revolutions connected with changes of governments. The two trigrams making up the hexagram are the same two that appear in K'uei, Opposition (hexagram 38), that is, the two younger daughters, Li and Tui. But while there the elder of the two daughters is above, and what results is essentially only an opposition of tendencies, here the younger daughter is above. The influences are in actual conflict, and the forces combat each other like fire and water (lake), each trying to destroy the other. Hence the idea of revolution.
