Its actually not a single building. The road next to Diwang Building is the Bao'an Bei Lu. If you drive down that long road, after a couple of km, you start seeing big shop/showrooms selling home decoration stuff. If you go further down, you will see the toys market and the songang art and craft market, further down its the auto market for second hand cars, and towards the end of the road you will find HOBA, Kinhome, B&Q and the big Geramn supermarket (i think its called metro??)
