So they're testing the concrete again. Three blocks, public housing, Tung Chung, still being built. The Housing Authority says the quality "requires further testing and review." That's the official line. Translation: something in the mix didn't look right and now everyone's waiting to find out how bad it is.

Look, we've been here before with concrete scares in this city, and the pattern is always the same. Someone finds an anomaly, the buildings get flagged, families who already queued years for a flat unit start doing the maths on whether their move-in date just quietly disappeared. Nobody's said these three blocks are unsafe. Nobody's said they're fine either. Until the retest comes back, the people who applied for these flats just sit there, not knowing if the building they're waiting on is solid or somebody's cost-cutting problem.
