It seems that the provided Twitter post does not relate to a maintenance report feedback for a public flat house. The post appears to be related to a fitness event or competition in Singapore, specifically the "Singapore MensPhysique 2019" and "Fitness Movement Physique War 2019". Therefore, the answer is "False" for the relatedness and "type" as "fitness event" or "competition", and "explanation" as "not related to maintenance report feedback for public flat house".
