It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house. The term "shenlong wall" is not a common term used in public housing context, and "Amoy Street" is not a specific location associated with public housing in Singapore. Therefore, it is unlikely that the post is related to a maintenance report feedback for a public flat house.
