It seems that the Twitter post "dinner han" does not relate to a maintenance report feedback to a public flat house. It is not clear what this post is referring to, as it is a single character and does not contain any context or information that would suggest it is related to maintenance or public housing. Therefore, the answer is "relatedness": False and "type": "none".
