I will stay in skyline plaza hotel Tongfu Road and will goto CIFF'14 in Guangzhou. Please guide which bus route ?

You must refer to the 2014 China International Furniture Fair. Well then, the fair will be held in the Pazhou Complex. You can walk from your hotel for around 1,200 meters to Guangdong pharmaceutical University General Station to catch Higer Education Mega Center Special Bus Line 3 (大学城专线3路) to Canton Fair Complex or Pazhou Complex directly.

Or you can also take suwbay to get there. From your hotel, walk to the 2nd Workers' Cultural Palace (Shi Er Gong) to take subway line 2 to Changgang, where transfer to line 8 to get off at Pazhou Station which is within walking distance to your destination!
