On a recent stormy Sunday, domestic helpers on their weekly day off were seen hastily erecting tents and laying out plastic sheets under footbridges and inside transport hubs in Hong Kong’s Tsuen Wan district as they sought refuge from the downpour. Dozens of tents were pitched around the pillars of the footbridges, while other groups crowded onto narrow concrete platforms inside a bus terminus. Many leaned against metal railings or sat on the ground, laying down blankets and carving out spaces.
