A member of the public waves the Chinese and Hong Kong flags as Peoples' Liberation Army (PLA) soldiers stand in the background at the Ngong Shuen Chau Barracks in Hong Kong on July 1, 2015, to mark the 18th anniversary of Hong Kong's handover from Britain to China. July 1 is traditionally a day of protest in Hong Kong and also marks the anniversary of the handover from Britain to China in 1997, under a "one country, two systems" agreement.
