It seems that the Twitter post you provided does not relate to a maintenance report feedback for public flat houses in Singapore. The post simply expresses happiness and pride in the country's 56th birthday and the anchorvale plains. Therefore, the answer is that the post does not relate to a maintenance report feedback for public flat houses.
