lobf, I actually think the Chinese numbers are partially true. A lot of famous battles were pretty deep into China. If your army only has to travel a couple hundred miles from where it was levied, it be pretty easy to keep it supplied vs. say Persia and their 1 million man army invading Greece (which is a good example of early propaganda. "Hey bitches, **** with us and you'll have a 1 million man army on your door step, so surrender and submit.")
