In Chinese culture, '南' (Nán) refers to 'south,' which carries various symbolic meanings in traditional beliefs, and '姑娘' (gū niang) means 'girl.' Thus this nickname portrays a girl who hails from the south. The character '一' here implies she's one of the kind. It suggests freedom, independence, and possibly the uniqueness of the girl.
