I suppose they wouldn't as this don't make much sense from the economic
POV. As topic-starter (sorry, I don't speak Chinese, and can't read his
name) said, it makes no sense to use exit-nodes located in China to
avoid the Great Firewall.
Don't forget it shouldn't necessarily be caused by some purposeful
Chinese government's actions to poison the Tor network with 'fake'
nodes. Even if Tor-client uses some legitimate exit-node located in
China, she will get censored content just because that's what exit-node
is receiving from the ISP.
