北海浪人南海故人
[bĕi hăi làng rén nán hăi gù rén]
Literally meaning 'Rogue from the Northern Sea and Old Acquaintance from the Southern Sea', this name has the nuance of being a traveler or wanderer (浪人 - a rogue) and at the same time an old friend. This could hint at someone who wanders but cherishes memories of the past or maintains long-standing friendships across great distances.
