approach, most notably with the construction of Xinjiang internment camps. The spectre that Hong Kong may similarly be brought to heel became an important element in the protests. Anti-mainland sentiment had begun to swell in the 2010s. The daily quota of 150 immigrants from China since 1997, and the massive flows of mainland visitors strained Hong Kong's public services and eroded local culture; mainlanders' perceived arrogance drew the scorn of Hongkongers. The rise of localism and the pro-independence movement after the Umbrella Revolution was marked by the high-profile campaign for the 2016 New Territories East by-election by activist Edward Leung.
