It seems that the Twitter post "longkang walk singapore" does not relate to a maintenance report feedback to public flat house. The term "longkang" is likely a colloquialism or slang term used in Singapore, and it does not appear to be related to any specific topic or issue related to public housing or maintenance reports.
