Where do Jiangxi cousins from other provinces come from? Good or bad?

Old cousin, also known as old cousin, is the name of Jiangxi people for their fellow villagers in the same province, with certain intimacy. Cousin Jiangxi has also become a kind name for Jiangxi people from other provinces. In addition, some people who immigrated from Jiangxi to other provinces from Ming and Qing Dynasties to modern times also kept the title of "old cousin", such as Hunan and northern Fujian. But now it's a bit derogatory.
