Entering the Rmbox Mall in Wangjing,one of Beijing's largest communities in its northeast suburb,the first-time shopper to the four-storey,110,000-square-meter shopping center might doubt the mall is even open for business.A majority of the nearly 100 store fronts are dark and vacant with "For Lease" ads draped across each space.Stores that are open have more shopping assistants than customers perusing the shelves."Business has been bad since it opened in 2008," said Wang Wei,a resident living nearby.
