Over the past 40 years, the fishing village of Shenzhen has been reborn as a futuristic metropolis bursting with factories. Bloomberg Businessweek's Ashlee Vance travels to the heart of China's tech revolution to witness this new reality firsthand, as part of a three-episode exploration of the city. In part one of Hello World Shenzhen, Vance gets a worker's view of life in a startup and then explores one of the city's famous electronics markets to learn how people survive (and in some cases make fortunes) in such a frenetic, competitive environment.
