Throngs of shoppers are seen in front of the Shenzhen Joy City shopping mall in Bao’an District on its opening day Saturday. The 250,000-square-meter complex welcomed more than 420,000 visitors and logged nearly 20 million yuan (US$2.79 million) in sales volume, excluding Apple products and cars, on its opening day. Joy City — China Oil and Foodstuffs Corp.’s flagship retail brand — merges youth culture with high style. Since its 2007 debut, it has rolled out seven malls across six Chinese cities, with Shenzhen the newest addition.          Shenzhen Economic Daily
