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.

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".
