Zhou Jinzhong, 25, from Henan province, stands outside an apartment where parents who say their children were killed or made sick by tainted milk powder gather ahead of a memorial for the victims on the outskirts of Beijing September 11, 2009. China was shaken last year by revelations that a toxic chemical added to substandard milk to allow it to pass quality controls had made nearly 300,000 children sick and killed six. Zhou said he lost a daughter who drank the tainted milk. REUTERS/Nir Elias (CHINA HEALTH POLITICS)
