 Where did they keep their strings of cash, anyway?

No idea where they kept their cash, but I think you definitely
need to rework the 'pocket money'.
Playing with the history, the Zhou would have used either
bronze shell or bronze spade (bu) coins.
so maybe the answer (and no attempt is made at meter here)
is to go for something like

Some who build, skimp, stopping lower
than they’re bidden, and yet others
because they receive a bu/shell for each stone
laid will always build too high


And how about changing 'his' to 'the' in L1?


Best, Knot.
