In this photo taken Sunday, Sept. 2, 2012, promotional posters of Legislative Council election candidates Christopher Lau Ka-hung, left, and Shiu Yeuk-yuen, second left, from the pro-democracy People Power are displayed at a park in Hong Kong. China's territory of Hong Kong has a high degree of autonomy, freedom of the press and limited democracy, but its politics remains highly constrained by Beijing's wariness over threats to its authority.
