Hexagram 44 of the Yijing, or the Book of Changes. This hexagram consists of one broken line at the bottom with five solid lines on top. Gou means "encounter," and the "judgment" reads, "Encounter is such that the woman is strong; it would not do to marry this woman." For more information on this hexagram, see Richard Lynn, tr., The Classic of Changes (New York: Columbia University Press, 1994), pp. 410-6, or Wilhelm/Baynes, tr., The I Ching or Book of Changes (Princeton, Princeton University Press, 1977), pp. 170-3.
