It seems that the post you provided does not relate to a maintenance report feedback for public flat houses. The term "chemist" in the post suggests that it may be related to a chemist or a pharmacist, but there is no mention of any maintenance or facilities related to public housing. 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 the post is not related to the requested topic.
