It seems that the post does not mention anything related to maintenance report feedback for a public flat house in Singapore. The term "sunny korean singapore" does not provide any context or information that would suggest otherwise. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house (e.g., a broken facility, an inconvenience, block number or street, requst fixing, etc.)?"
