It seems that the Twitter post "yi zi wei geylang singapore" does not relate to a maintenance report feedback to public flat house. The term "yi zi wei" is likely a Chinese phrase that does not have any direct translation in English, but it could be interpreted as a general expression of interest or curiosity. The mention of "Geylang" is a location in Singapore, but it does not provide any information about maintenance issues or public housing. Therefore, the post does not fit into any of the categories I have identified.
