Nine in the third place describes being held in place by the people one is responsible for, and it is one of the classic's more practical lines. The querent is trying to step out of a situation and is bound by ties that are not adversarial. The text calls this distressing and dangerous, then declines to recommend any decisive stroke, and the commentary is explicit that no great act is available. What is available is care, at the domestic scale the line names.
The vocabulary of servants and concubines is the household register of the period the text was set down in, and it is reported here as the text has it. Read for what the line is doing with it rather than for the arrangement it assumes, the counsel is that the obstacle is made of obligations to particular people, and that obligations of that kind are discharged by continuing to meet them rather than by any single resolution a querent can perform and be finished with.
When the line changes, the lower trigram Gen becomes Kun and the figure becomes Standstill, King Wen 12, in which heaven and earth move apart and nothing passes between them. That is the warning carried underneath the line's qualified good fortune. A retreat that stops being conducted, and simply stalls with the ties still attached, hardens into a blockage, and the difference between the two outcomes is whether the small daily obligations are still being kept.
