I'd like to know whether there are places near Shenzhen to shop?

For shopping, the best places is Dongmen area near Laojie Subway Station.
Shenzhen is a famous for its cheap eletronic products and you can go to Huaqiangbei area to see.
If you want to buy something in bulk, would you tell me what kind of product do you want to buy? If you can tell me, I may tell you a wholesale market for you of your specific product.
