It seems that the post you provided does not contain any information related to a maintenance report for a public flat in Singapore. The term "chang cheng" could potentially refer to a location in Singapore, but without more context, it is difficult to determine the exact meaning of the term. Additionally, the mention of "vegetable rice" and "Singapore" does not suggest that the post is related to a maintenance report for a public flat.
