Developed by billionaire Deng Hong's Entertainment and Travel Group (ETG), nearly 400,000 square metres (4,300,000 sq ft) of the building is devoted to shopping. It also houses offices, conference rooms, a university complex, two commercial centres, hotels, an IMAX cinema, a "Mediterranean village", a pirate ship and skating rink.
