It seems that the tweet does not relate to a maintenance report feedback for a public flat house. The tweet simply mentions "embassy republic korea singapore" without providing any context or information related to maintenance or public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the tweet does not belong to any of the categories mentioned in the question. The "explanation" field provides a brief explanation for why the tweet does not match the criteria.
