    ]

It seems that the post does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post only includes a photo of Shangri-La Singapore, which is a luxury hotel in Singapore, and does not contain any information or context related to maintenance report feedback for public flats. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
