Guardian report on Chinese manufacturing in Shenzhen

It's a slightly old story now but amazing to read how much China has changed in the past 30 years and the sheer scale that comes from having hundreds of millions of workers available.

In Shenzhen, you have everything you need to turn a sketch on a napkin into 100,000 smartwatches, bike lights or drones, all shipped to Amazon or Argos in time for Christmas 2014.

Simply amazing.
