It seems that the tweet "mask compound grand copthorne waterfront hotel" does not relate to a maintenance report feedback for a public flat house. The term "mask compound" and "grand copthorne" do not seem to be associated with any public housing facilities, and "waterfront hotel" is not a type of housing. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
