if i stay in zhongshan ba, and want to go to Foshan kids wear wholesale market, how to?

Hi, do you mean the Zhongshanba Station of Guangzhou? If so, here is my suggestion about the route:
You need walk to Zhujiangqiaojiao first. There you can take bus no. 71 to the terminal station. Then walking to Xilang MTR Station to take subway line Guangfo Line to Zhaoan Station. Then you can walk about 700-800 m to reach the kids wear wholesale market.
