It seems that the tweet "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 facility. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house in Singapore.
