People often send things to Xie Guomei. Sometimes they're from close friends, sometimes from people she knows, and more often from strangers.
Xie Guomei is used to people coming and going. She doesn't want to leave too many traces behind in this world, but those people don't feel the same way. They seem to love interacting with her, eager to leave their own distinct footprints in her otherwise uninteresting life.
So Xie Guomei decided to open a collection room, where she could sort through and keep some of the things from different people, then look through them whenever she felt like it.
