how to go to Na'nan Stationery and Sport Goods Wholesale Market in Guangzhou?

Hey, you may refer to Nan'an, not Na'nan, right?
If so, you can take subway line 5 to Zhongshanba, get off from exit D, and then walk northwards for about 650 yards to reach there.
Or you can go to this place: Haiyin Ersha Sports Boutique Gallery. It is located in Datong Road in Yuexiu District, near Dongshanhu Park. You can take subway line 6 to Donghu. After arrival, walk to the south to the intersection of Donghu Road and East Yanjiang Road, and then turn to east to Datong Road to reach.
