Where is the best shopping place at Shenzhen and how to get there from Hong Kong ?

Shenzhen Dongmen Pedestrain Street is a good place for shopping.
From Hong Kong to the Dongmen, you need to take the East Rail Line from Hong Hum to Luowu station and then pass the Luohu Port. After that, you can take the Luobao Line to Laojie Station. When you go out of the station from Exit G, you can find it easily.
