It seems that the post does not mention any specific information related to maintenance report feedback for a public flat in Singapore. The term "shabu sai tampines singapore" does not provide any context or details that suggest otherwise. Therefore, the answer is "no" 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.)?"
