邮差客人
[yóu chā kè rén]
Postal Guest:'邮差' refers to postman and '客人' means guests. Postmen usually deliver messages and letters, making it a very romantic role especially during ancient times or in novels when they carried messages of love. The online name suggests someone special who comes into one's life temporarily leaving memories like a letter delivered by a postman, and there is sometimes even the metaphor of being an outsider in a place, not belonging but accepted.
