I play the card game Magic the Gathering and have long known that cards showing skeletons and bones receive alternate art for distribution in China. Here’s an example. I just learned that Chinese copies of World of Warcraft have sprites of undead altered as to not show bones.
Why does the Chinese government object to images of bones? I understand that they’re sensitive about political and religious stuff, but what’s the deal with bones?
Isn’t it a Buddhist thing? I thought I remembered something about that being why medieval Japanese women stained their teeth black, and why they tend to put their hands over their teeth when they laugh - your teeth are bones sticking out of your head. Is that totally off-base?
Apparently exposed bones/skeletons are a bit of a taboo in traditional Chinese society.

In World of Warcraft dead player bodies decay to bones, except in China, where they turn into graves.
Because only uncivilized barbarians expose their dead and let the dearly departed rot down to their skeletons, duh. 
This Chinese doper thinks that it may have something to do with Confucianism, where filial piety is supposed to be shown to your previous generations, even if their physical bodies are six feet under.
Only criminals had their bodies displayed to the public, so obviously that was something to avoid if you were a law-abiding citizen (and most of the time even the condemned were eventually allowed a burial if enough money got passed under the table).
Just about the only thing worse than not getting a decent burial was to be beheaded, because you no longer had an intact corpse. (Which I suppose affected how you looked in the afterlife, but I’m a little fuzzy about that part.)
