i am stay near by Jiangtai road subway station any idea any bank of china and bank of guangzhou branch there in Guangzhou?

The closest branch of GZ Bank is the one on Jiangyan Road and the branch is located at NO. 21, Jiangyan Road.
From the Jiangtai Subway Station, you can walk along the Nanzhu Road to reach Jiangyan Road and then walk along that road to find the branch.
The bank of china is also located on the Jiangyan Road. From the bank of GZ, you still need to walk along the Jiangyan Road to find the bank of china.
