It seems that the provided Twitter post does not relate to a maintenance report feedback for a public flat house in Singapore. The post mentions "chinatown mrt interchange ne4 dt19 singapore", which is a location in Singapore, but it does not contain any information about a maintenance report or feedback related to a public flat house. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not belong to any category related to maintenance reports. The "explanation" field contains a brief explanation for why the post is not related to the requested topic.
