Zhang Ding Ling, 23, is seen as she goes through the so-called "double eyelid surgery", which adds a crease to the eyelids to make the eyes appear larger, in a plastic surgery clinic in Shanghai November 4, 2007. Zhang received the procedure as a present from her parents for her 23rd birthday. Chinese government officials estimate that $2.4 billion was spent last year on plastic surgery procedures, with 1 million operations taking place. Double eyelid surgery is the most popular cosmetic procedure in China. Picture taken November 4, 2007. REUTERS/Nir Elias (CHINA)
