When you use Google maps, don’t choose satelite imagery. That satellite image was taken in 2003 and no update ever since then. Which means there are so many changes happened in Nanning city makes the image no longer accurate.
Suggest you to use Map mode, that map is provided by Chinese navigation Company and it’s more accurate.
Here is the google map of Nanning marked by me. It will be updated as this website updating.
