bus station adress to go to yiwu from gangzhou

There are three buses from Guangyuan Bus Station, one bus from Provincial Bus Station, one bus from Fangcun Bus Station and one from Tianhe Bus Terminal.
The Guangzhou Bus Station is at No. 283, Guangyuan Middle Road. The Provincial Bus Station is near the local railway station. Fangcun Bus Station is at No. 51, Middle Huadi Avenue in Liwan District. The Tianhe Bus Station is at No 633, Yanling Road.

I suggest you to Guangdong province Bus Station. It close to Canton Railway Station.
