A tragic fire has ripped through Hong Kong’s Wang Fuk Court housing estate, killing at least 128 people and leaving hundreds missing. But amid the horror, a vibrant wave of help has exploded from the city’s grassroots groups. Around Tai Po, where the fire happened, restaurants, churches, and gyms have quickly turned into shelters offering clothes, food, and vital information. People on the ground and online have instantly jumped into action. Volunteers from every corner seem to remember their heroic moments from the 2014 and 2019 pro-democracy protests. Michael Mo, a former district councillor now in the UK, summed it up perfectly: “Since the two movements in 2014 and 2019, citizen-led supplies mobilisation have become part of our muscle memory.” Digital tools are shining stars here: a crowd-sourced web app lists every apartment and resident’s safety status, helping track who’s safe or still missing. Another website displays an interactive map of supply stations in Tai Po, while volunteers organize their shifts through a special platform. Calls for help fly nonstop on Telegram groups for drivers, helpers, and fire support, packed with thousands of members ready to jump in. Fundraising is booming too. The government quickly kicked off a “Support Fund for Wang Fuk Court in Tai Po” with a massive HKD 300 million (£29 million) donation, alongside other donation channels lighting up across the web. The Hong Kong Red Cross, facing 8 to 10 days' worth of blood supplies, urged people to book ahead for future donations. Meanwhile, a group of local lawyers is preparing to give free legal help, readying FAQ guides in Chinese, English, and other minority languages. They want to clear the path for victims facing tenancy, employment, or land law troubles thanks to the disaster. Among the victims are at least two Indonesian domestic helpers, highlighting the fire's tragic reach. What caused this blazing tragedy? Residents raised alarm for over a year about fire dangers linked to bamboo scaffolding and green netting surrounding these seven towers during construction work. Officials also pointed fingers at flammable Styrofoam covering elevator windows. Even worse, fire chief Andy Yeung confirmed no alarms rang in any tower during the fire. Shock waves hit harder when three people from the contractor Prestige were arrested for suspected manslaughter—especially after Prestige was convicted of safety offences in 2023 before they took over the renovation. The company has still not spoken out. Meanwhile, a web project is archiving homeowners’ association meeting notes, where worries about the renovation contract had surfaced. The labour department had told residents last year the fire risk was low but had also warned the contractor many times about unsafe work practices. This disaster has unleashed a storm of questions, grief, and fierce community spirit. Hong Kong’s heartbeats are united, not just in mourning, but also in action, hope, and the fight for safety and justice.
