Engadget's European correspondent Richard Lai is exploring the gadget markets of Hong Kong

You may have already seen the large range of gadgets -- both old and new -- in Hong Kong, but the small presence of KIRFs there does make things a tad less exciting. Want more? Turns out all you need to do is grab a Chinese visa (or a border pass if you're a Hong Kong or Macau resident), take a train ride up north and you'll reach Shenzhen for all the KIRFs you've ever wanted. In this second part of our China tour series, we'll be showing you around the Luohu Commercial City and the Huaqiangbei gadget heaven -- don't worry, there are still many genuine products there for you little angels. Oh, and we also popped into a Meizu store for some hands-on time with the notorious M8. Enjoy.
