It seems that the Twitter post "ши xian feng singapore" does not relate to a maintenance report feedback to public flat house in Singapore. The term "ши xian feng" is not a recognized term in Singaporean English, and it does not appear to be a reference to any specific location or issue related to public housing. Therefore, the answer is "relatedness": False, and the type is "none".
