A staff member displays the Chinese dissident artist Ai Weiwei's new sculpture installation "Baby Formula" which formed a map of China with cans of milk powder at a exhibition in Hong Kong Thursday. Ai Weiwei's work is inspired by the scandal over melamine-tainted milk powder in China 2008 which was reported to have affected nearly 300,000 children and causing six babies to die from kidney problems.
Due to the food-safety-conscious, Chinese people flock to Hong Kong to buy baby milk formula that cause shortage supply in the city. (AP Photo/Kin Cheung)
