It seems that the Twitter post "hilang shi tian xia singapore" does not relate to a maintenance report feedback to public flat house in Singapore. The phrase "hilang shi tian xia" is likely a Chinese phrase that does not have any direct translation to English, and the mention of "Singapore" suggests that the post is not related to any specific location or issue in Singapore. Therefore, the answer is "False" for the relatedness and "none" for the type, along with a brief explanation.
