Guangzhou has a modern subway system which services a large part of the city. For me, I wanted to get from Ghuangzhou East Railway Station to Pazhou where the Canton Fair complex is. It turned out to be pretty easy, just buy a ticket at the electronic vending machine which accepts coins, 5 yuan notes and 10 yuan notes.
I had to take line 1 to Tiyuxilu and then change to line 3 and then get off at Kecun and change to line 2 whose second last destination is Pazhou. When I walked out of the Pazhou Station I was right in the middle of trade fair city where the Jinhan Fair and Canton Fair Complex were located. The International Sourcing Expo is also nearby.
