It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post simply mentions the name of a restaurant, "ocean restaurant", followed by the name of a cat, "cat cora", and the location of the restaurant, "Singapore". Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
