It seems that the Twitter post you provided does not mention anything related to maintenance report feedback for a public flat house. The phrase "avalon memoriesofpast" and "marina bay sands" do not appear to be related to any specific maintenance issue or feedback for a public housing estate. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not possible to determine the type of feedback or issue mentioned in the post. The "explanation" field is left blank since there is no explanation for why the post does not relate to a maintenance report feedback for a public flat house.
