Where is best rate to exchange money near China South Railway Station?

Do you mean Guangzhou? It says online there is a United Money office in the airport, 3F, Gate 7 in the international departure hall. You can try this office

Thank you Wallace. Yes, the Guangzhuo airport. I'll look at the rates there. Is there a Bank of China on Beijing Pedestrian Street that I can change money at? Bank rates are supposed to be the best at banks. If so, what are the hours open of banks in Guangzhuo

There are 2 office shows online, one at No 67-69 Wende Rd, the 1F of Jinde Mansion. The other one at No. 60 Guangda Rd. Tthis 2 should be not too far. You may have a try to find them.

Thank You Wallace, you've been very helpful. We will look for them
