>> Old school radios and cassette players, these are the kinds of gadgets Wang Wei Chun assembled in the 80s, though back then, she had no idea of the small role she was playing in China's economic boom. Wang moved to the southern city of Shenzhen when she was 21, and started working for Sanyo, a Japanese electronics firm that had just started manufacturing there.
> When we arrived here, there was only one road. There was no such things as skyscrapers, buildings were two to three floors high.>> Sanyo was the first Japanese company to set up shop in Sinjin, after China embarked in its reform and opening up policy in 1978.
Migrant workers like Wang, helped make made in China a household label around the world, fast forward more than 30 years. And while the production lines are gone, the factory still stand.

The city's economic output even surpassed that of its next door neighbor Hong Kong, for the first time last year. According to state media, Shenzhen expects to have the largest metro network in the world by 2030, but there's a dark side to this mega city's speedy development, the heavy human toll.
A recent Reuters report revealed, that protests have sprouted throughout the city, with former workers wanting compensation from the local government. Some have deadly diseases that they say is a result of the work they carried out, and that they won't survive long. A Shenzhen government spokesperson referred questions on workers' compensation to other government departments, who also declined to comment.
