Is there any way to find out the specific reason the book was not allowed to be published?
My guess is that the chinese publisher didn't want to pay royalties, and this was a convenient way to get a good quality copy of the book for printing without having to share profit.
I wonder if it's a subtle psychological trick to not associate red with negative connotations (such as "declining profits", "stop", "blood") because the color red is part of the CPC's identity makeup.Or maybe it's just a cultural thing, like how they wear white when someone died and black to celebrate a birth/life (I'm not sure if it is a chinese custom however, but I know it's an asian custom).
