陈南城北
[chén nán chéng bĕi]
A person named Chen (a common Chinese surname) may use this as it suggests being someone far away from others since Nan means 'south' and Cheng means 'city'. It reflects being geographically distant but also emotionally separated from the rest of the world. It could be taken more literally too, referring to someone located specifically north of a city southward. For a western comparison it would be like saying John Northof Boston.
