It seems that the Twitter post "onpoint chinatown" does not relate to a maintenance report feedback to a public flat house. The post does not mention any specific issues or concerns related to maintenance, such as broken facilities, inconveniences, or requests for fixing. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "This is not related to public housing or maintenance issues."
