It seems that the Twitter post "korea myongdong" does not relate to a maintenance report feedback to public flat house. Myongdong is a district in Seoul, South Korea, and it is not a specific location or facility related to public housing. Therefore, the post does not fall under the category of maintenance report feedback.
