Coco Au poses for a photo outside her “coffin” home in Hong Kong, China, July 10, 2024. These windowless spaces are still more cramped and just big enough, at 15 sq ft (1.4 sq m) to 18 sq ft (1.7 sq m), for people to sleep in and store a few personal items. But lack of ventilation forces them to leave open the small sliding doors to their “coffin” homes, denying them any vestiges of privacy. REUTERS/Tyrone Siu
