Amazon's Kindle devices are selling in China because the e-reader allows users to log on to banned sites such as Twitter and Facebook, reports say.
The device bypasses the infamous Great Firewall, making it popular on the so-called grey market according to the South China Morning Post.
Officially the Kindle is not available in mainland China.
But a quick search of Chinese auction site Taobao reveals hundreds of them on offer.
