It seems that the Twitter post "chinatown" does not relate to a maintenance report feedback to public flat house. The term "chinatown" is a general term used to refer to an ethnic Chinese urban area, and it does not mention any specific issue or problem related to public housing or maintenance. Therefore, the answer is "False" for the relatedness and "none" for the type, along with a brief explanation.
