It seems that the Twitter post "18 tai seng" does not relate to a maintenance report feedback to a public flat house. The term "tai seng" is not a common term used in public housing contexts, and it does not convey any information about a specific issue or facility that needs maintenance. 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 context.
