It seems that the post does not contain any information related to maintenance report feedback for a public flat house in Singapore. The post only shows a photo of a person (samjin) in Singapore, but it does not provide any context or information that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
