Hello, I suggest you take the subway and get off at Xingang East, but don't leave the station. Ask the staff 10. 1 which station is convenient to get off at the lobby, and the staff on the subway will know. Because Pazhou Convention and Exhibition Center can actually get off at Xingang East or Pazhou Station, but it is not clear which station to go to.
In addition, the stops of Guangzhou Line 8 are attached: Fenghuang New Village-Shayuan-Baogang Avenue-Changgang-Xiaogang-Zhong Da-Lujiang-Kecun-Chigang-Modiesha-Xingang East-Pazhou-Wanshengwei.
I hope my answer can help you, thank you.
