Hello Mr. yusuf:
I recommend you to stay in a hotel near to the railway station ,it might be much more convenient to go to the whole sales market from there, because the whole sales markets of construction and furniture materials like (marbles, wooden doors, wooden tiles, ceramics, bath rooms, furniture etc) are located outside of city, if you want to buy them at a low price, I suggest you to go to Foshan.
You can buy the mobile accessories at the nanfang dasha ,gangding ,tianhe cheng of Guangzhou or in Shenzhen;the price in Shenzhen is much more cheaper than in Guangzhou.

hi,

You can go to Shiwan ceramics city in Foshan, many of our african customers go there for marbles, tiles, jacucci, and go to Lecong for the furniture.

If you have problems finding the market, you can feel free to contact me. I will be glad to help.
