It seems that the post you provided does not mention anything related to a maintenance report for a public flat house. The post simply mentions a photo of the Yishun Pond Lookout Tower, which is likely a tourist attraction or a scenic spot in Singapore. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
