It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house. The term "nanyang dentist" does not appear to be related to any specific context or topic that would suggest otherwise. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not possible to determine a specific type of feedback or report based on the provided tweet. The "explanation" field is left blank since there is no additional information to provide beyond the initial assessment.
