Hi,where can take bus here in zhongshan ba going to dong guan hua nan mall terminal building.

Do you refer to Zhongshan Ba subway station in Guangzhou?
If so, You can take the subway line 5 from Zhongshanba to Guangzhou Railway Station. Take the Exit D2 and walk about 220 yards, you will reach the Provincial Bus Station, where you can take a direct bus to Dongguan. The bus will stop at Dongguan General Bus Station, which is about 1.2 miles from the Huanan Mall. From the bus station, you can take the bus No. 50 to the mall directly. If taking a taxi to cover this distance, it may cost you CNY10.
