Be careful about the voltage. China uses 220 volt system with a variety of plugs (British standard, two-prong polarized, two-prong unpolarized, three-prong, EU standard, etc.) My apartment in Shanghai had four different outlets on the walls. If electronic market is primarily for foreigners, still be care about the voltage. Shenzhen is my next destination in China (but for work); maybe I'll see about the markets; thanks.
