As a divinatory line, nine at the fifth place of Coming to Meet reads within the hexagram's overall concern with a bold, strong female met unexpectedly; not good to marry such a one, since she should not be long associated with. The line occupies a place proper to its own nature in the classical doctrine that odd places favour a firm, yang line and even places favour a yielding, yin line. It is also one of the two central lines of the hexagram, the place classical reading treats as the most balanced regardless of the line's own character. Its own text, that a medlar tree overspreading a melon beneath it, and if he keeps his brilliant qualities concealed a good issue descends as if from heaven, is the particular fortune assigned to this one stage of the situation, not to the hexagram as a whole.
The fifth line corresponds by classical convention with the second line, and the two do not correspond here, since both lines share the same character. Read together with the trigram it belongs to, Qian in the upper position of the figure, the line marks the ruling stage of the hexagram, the place classical reading treats as its centre of authority, one stage in the six stage movement the hexagram traces from its first line to its last.
A change at this line, from yang to its opposite, is the mechanism the tradition uses to move from one hexagram to another. Flipping the fifth line of Coming to Meet turns Qian into Li while the other trigram, Xun, stays as it is, which yields Coming to Meet's changing partner, The Cauldron (King Wen 50), the hexagram this line is recorded as transforming into.
