It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "shanghai tang singapore" does not contain any keywords related to maintenance reports or public housing, and does not suggest any specific issue or problem that would warrant a maintenance report. Therefore, the answer is "False" for the relatedness question.
