>>102437215China has a bunch of extremely vague censorship laws, so you've got to walk on eggshells constantly when making any kind of creative work. There's an urban legend about the Chinese being afraid of skeleybones, but the truth is they've just got a censorship against the "occult". Nobody knows what it means exactly, and they don't want to run through the trouble of running everything by their government, so they play it extremely safe.
You've got to remember that China is still a weapons-grade shithole despite its money and power. Imagine how fucked western media would be if anything that could be construed as a slight against the government got your production axed and your creative team sent to the gulag. That's China.
