Grand Duke issue for a builder

Frankly, in my opinion, I widely consider what you mentioned under a broad term: "Occupational Hazard".
For example, drawing a parallel to you.
Even we geomancers also may fall into "Occupational Hazards" once in a while. Here, we would bring along our luopan. And once in a while; during our visits; meet a home that is "dirty" or "unclean" (belonging to those of the other kind).
From the safety aspect; just take extra care to minimize personal exposures to risks. Otherwise: it is an occupational hazard".

Hello Mr Lee, Fixing houses is
my business so it does not
seem practical for me to wait
for next year to finish the
work of a house in order to
avoid offending Grand Duke.
I wonder what I can do
to avoid offending Grand Duke,
while at the same time can
finish the renovation. I
have searched your website but
have not succeeded in finding
such information. Thank
you in Advance for your
advice.
