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 sushiro suntec, which is likely a food establishment or a location. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "The post does not relate to a maintenance report feedback for a public flat house."
