I wanna know most near subway station to baima market and haiyin electronic market in Guangzhou.

Around the Biama Market, the nearest subway station should be the Guangzhou Railway Station. The market is about 150 yards from the Exit G.

Do you refer to the Haiyin Electronic market located at No. 56 – 58 West Donghu Road?
If so, the nearest subway station is Donghu Station. The market is located beside the Exit B2.
