HONG KONG, HONG KONG SAR, CHINA - OCTOBER 02: A little girl writes on a stick-up note to be hung on a wall, nicknamed the 'John Lennon' wall, together with hundreds of messages written by demonstrators on Government buildings in Admirality, Hong Kong, on October 2, 2014. The 'Umbrella revolution' or 'Occupy Central' is a civil disobedience movement that began in response to China's decision to allow only Beijing-vetted candidates to stand in the city's 2017 election for the top civil position of chief executive. Thousands of pro-democracy supporters are calling for open elections and the resignation of Hong Kong's Chief Executive Leung Chun-ying. (Photo by Lucas Schifres/Getty Images)
