In the Teochew dialect of Chaoshan, “our own people” sounds roughly like gaginang. Some write it 胶己人, but the linguist Lin Lunlun says the correct form is 家己人.
An article on Chaoshan identity describes the effect of the word among Teochew people far from home: “Wherever you go, if you say one word, gaginang, there is no one who will not help.”
