It seems that the Twitter post "song lang garden" does not relate to a maintenance report feedback to a public flat house. It is not clear what this post refers to, as it is a song title and does not provide any context related to maintenance reports or public housing. Therefore, the answer is "relatedness": False and "type": "none".
