This hexagram is named "Fu," meaning return. It reveals the inevitable law of nature where yin recedes and yang, representing uprightness and righteousness, gradually returns, signifying the continuous cycle of creation and renewal in heaven and earth. It also illustrates the principle of returning to goodness, pursuing benevolence, and adhering to the righteous path, warning against straying from it. Fu signifies cycles and repetition, meaning that good things will repeat, but bad things can also come back. Thunder represents spring and the first lunar month of Yin. The spring thunder shakes the earth, symbolizing the rejuvenation of the land and the cyclical nature of things. From its爻 (lines), this hexagram has one yang line below five yin lines, signifying the return of yang after reaching its extreme (yin). It is the reverse of the hexagram Bo (Stripping), where Bo moves upward and Fu moves downward, hence its name "Fu."
