From the perspective of the intersecting positions of this line, both the second and third lines represent progress, while the fifth position signifies reaching the peak of progress. This symbolizes a person being in the position of an emperor, with their career at its zenith. However, nothing in life can progress indefinitely without retreat. Especially when one ascends to the esteemed position of "nine five" (九五之尊), creating a great and flourishing enterprise, there must inherently be both advancement and retreat. Retreat is for the purpose of better advancement. Therefore, this line depicts the dragon retreating back to the abyss, which serves as the foundation for "the dragon leaping." Thus, the phrase "the dragon leaps in the abyss" represents a necessary retreat before further action in the heavens. King Wu, after gathering 800 feudal lords at Mengjin, still chose to withdraw his troops and return home. On the surface, it was a retreat, but in reality, it was a preparatory exercise for the grand assembly of the feudal lords two years later, which ultimately led to the overthrow of King Zhou. Hence, in conducting oneself in the world, one should not only focus on moving forward but also understand the necessity of retreating when appropriate. A well-timed retreat can be more beneficial to life than blind advancement.
