Neon signs are the sparkling jewels that light up the Hong Kong night sky. Signs for restaurants, shops, and hotels once jostled for space above sidewalks to create a unique cityscape. But in recent years, older signs are being removed out of fear they might fall. They've been replaced by cheaper and simpler LEDs, and up to 90% of the city's neon has vanished. Craftsman Wu Chi-kai has spent 35 years making these signs and now works with a preservation society to hold workshops and tours aimed at caring for the neon signs that remain.
