Ha, Cixin Liu! At one point I've read everything by him available in Polish, but I don't remember this specific short story. I guess I need switch to English :)

By the way, reading a "double-translation" (Chinese -> English -> Polish) is fascinating--at times it's more than obvious that what you're reading is not what the author has written, but you have no idea at all what the original concept was. (Unlike "single" EN -> PL translations, where I can often figure out the idiom or concept that was used in the original.)
