Does taking subway from Guangzhou Baiyun Airport to Huanshi Dong Lu, Yue Xiu incur min. cost or shuttle bus?

For Huanshi Donglu, it is suggested to take the airport express line 1 to reach Civil Aviation Ticket Office near the local railway station and then change to take the subway line 5 from the railway station to reach Zoo Station. Get out of the station, you will reach Huanshi Donglu.
For the Yuixiu incur min, I am afraid that I am not very clear about this place.
The cost for the shuttle bus is around 17RMB per person and the subway's fare is around 3RMB.
