Citing a deadly November 18 fire in one of Beijing’s many shantytowns, city officials are implementing a 40-day cleanup campaign to rid the city of unsafe structures. Most of these serve as homes to the 8.2 million permanent migrant workers living in the capital. The campaign aims to clear 40 million square meters of illegal housing in what will be the biggest facelift since the 2008 Olympics. The force and timing of the campaign, though, is leaving thousands of migrants without homes at the onset of a frigid winter. Universal backlash on social media, from intellectual groups, and international rights organizations came quickly.
