The given Twitter post does not seem to relate to a maintenance report feedback for a public flat house. The post mentions "asiantour" and "japantour" which are likely golf-related events or tours, and "golf singapore" which is a golfing event in Singapore. There is no mention of any maintenance report or feedback for a public flat house. Therefore, the answer is a JSON object with "relatedness" set to False, "type" set to "none", and "explanation" set to a short explanation that the post is not related to maintenance report feedback for public flat house.
