It seems that the Twitter post you provided does not mention anything related to maintenance report feedback for a public flat house. The post simply encourages people to walk slowly and not backward, with no mention of any specific location or issue related to public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
