Soil is dug from the moat and piled up to form a wall, just as the way of good governance accumulates to bring about Peace; when Peace reaches its end, it is about to revert to Standstill (Stagnation), like the wall's earth crumbling and falling back into the moat.
The top is the end of Peace; Six at the Top, being a small man dwelling there, is about to enter Standstill. 'Do not employ an army': the ruler can employ his multitude because the sentiments between upper and lower are in communion and their hearts follow him.
Now that Peace is drawing to a close and the way of Peace is lost, the sentiments of upper and lower no longer communicate; the minds of the people are scattered and alienated, not following their superior—how could they be employed? To employ them would only bring chaos.
Since the multitudes cannot be employed, one only issues orders to one's own immediate entourage. Even if what one orders attains correctness, it is still shameful and distressing.
The 'town' in which one dwells refers to those close at hand; broadly speaking, issuing proclamations must begin with those near.
Whenever 'correctness brings misfortune' or 'correctness brings distress' appears, there are two meanings: in one, stubbornly clinging to this brings misfortune or distress; in the other, even though one attains correctness, it is still unfortunate or distressing.
Here it does not say 'correctness brings misfortune' but 'correctness brings distress,' because to begin issuing orders only when Standstill is imminent is shameful and distressing, yet the Standstill itself is not caused by issuing the orders.
