It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house. The term "diy ecg liao" does not make sense in the context of maintenance report feedback, and it is not a specific term used in the public housing industry. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because 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.
