In a postscript to the American edition of The Three-Body Problem / 三体, the author says:
In science fiction, humanity is often described as a collective. In this book, a man named “humanity” confronts a disaster
But I cannot recognize any character's name as being "humanity." Maybe the man who most clearly sees the disaster is Wang Miao (汪淼). I don't think that can be "humanity."
Is there a character whose name can be read as humanity? Or perhaps is Liu speaking metaphorically in the postscript?
