Zhou Jian, a 26-year-old folk dancer, dreams of a stage career, and he believes the Magic Kingdom can help him get there. Zhou recently made the 14-hour journey by train from Shanxi, China, to attend a jobs fair in Shanghai, where he hopes to land work at Walt Disney Co.'s 963-acre, 5.5 billion resort set to open June 16. He covets a role in the Lion King musical production that will be performed in Mandarin for the first time. The company's greatest business opportunity since founder Walt Disney bought land in central Florida in the 1960s. "I want to be famous before 30 years old," he said.
