Paramilitary police officers stop a woman as she protests on her knees in front of the Great Hall of the People, where the annual session of China's legislature, the National People's Congress, is currently being held, in Beijing on March 13, 2015. Each year during the annual legislative session petitioners arrive in Beijing hoping to air their personal grievances with Chinese leaders, only to be led away and often returned to their hometowns by police.
