The post mentions "prosperity salmon yu sheng delivered" and "jumbo seafood singapore", which do not seem to be related to maintenance issues in a public flat house. Therefore, the answer is "False" for the "relatedness" field, and "none" for the "type" field, with a brief explanation provided in the "explanation" field.
