Deng Xiaoping created the city from bucolic nothing in 1980 as the pilot of his special economic zone project. These zones were meant to create safe places for Western companies to do business—and they worked. Even though China is not the boom-country it was two years ago, favorable trade policies and cheap skilled labor lure companies and entrepreneurs from across the globe to Shenzhen’s nimble factories.

As of 2013, there were 22,000 permanent foreign nationals living in the city, and nearly 8 million others visiting every year. The expats range from the manufacturing-industry vet with a house and a spouse to the fresh-off-the-plane Kickstarter romantic with a pocketful of pledge cash to the English teacher who can’t tell a diode from a dinner plate.
