It seems that the post does not mention anything related to maintenance report feedback for a public flat house. The post only includes a photo of a diamond-shaped kitchen, which does not provide any information about maintenance or issues related to public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
