It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house. The term "mandarin gallery singapore" does not appear to be associated with any specific public housing estate or maintenance issue. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not related to any specific category. The "explanation" field provides a brief explanation for why this is the case.
