It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house. The term "ann siang hill" does not seem to be a specific location or facility related to public housing, and the post does not contain any information that would suggest otherwise. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
