Read structurally rather than through the marriage imagery, hexagram 44 has a clear and useful sense: an encounter with something that seems minor and is not.
The single broken line at the base is the whole content. It is one small thing under five large ones, and the hexagram's counsel throughout is that it should not be allowed to develop unattended. The Image tells the ruler to issue commands to the four quarters, which is an instruction about early and wide communication rather than about suppression.
The line texts sustain the theme. The first has the situation checked with a brake of bronze, and warns that letting it take its course brings misfortune, a lean pig that will certainly rage about. The second and fourth concern a fish in a container: contained, it is manageable; let out, it is not. The fifth has a melon covered with willow leaves, hidden lines, and something falling from heaven.
In practice the figure reads for the arrival of an influence, a person, an idea or a habit that is currently small and is going to matter. Whether that is welcome depends entirely on context, and the hexagram itself is more neutral than most commentaries make it.
The counterpart figure is hexagram 43, five yang lines with a single yin at the top: the same intrusion at the point of being expelled rather than at the point of entry. The two are inversions and the pairing is deliberate. Reading them together gives the full account: how such a thing enters, and what it takes to remove it once it has.
