Do you refer to the furniture or decoration materials? Anyway, you can go to Danan Road where you can find a professional street with the house decoration materials. Besides, Neew Taikang Decoration City is also a good choice. There you can find all kinds of house materials of different qualities. Take subway line 2 and get off at Haizhu Square Station. Then walk eastwards for about 200m and you will find the Decoration City.
