It seems that the post does not relate to a maintenance report feedback to public flat house in Singapore. The post simply says "hello singapore" and does not mention any specific issue or problem 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 given category.
