It seems that the tweet you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The tweet simply says "lit lit sin kallang singapore" which does not provide any context or information that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house in Singapore.
