    ]

The post does not relate to a maintenance report feedback for public flat houses. The term "rain vortex" and "waterfall jewel" suggest a natural phenomenon or attraction, rather than a maintenance issue. Additionally, the mention of "Changi Airport" and "world best airport" implies that the post is about an airport, rather than a housing complex.
