Okay, there are home / family rituals, which I see as basically harmless, though I chafe at the superstitious elements. Oh, you could argue that they serve to reinforce Confucian values, and are therefore evil, but it could just as easily be said to reflect those values--or more likely, both of them evolved in a kind of symbiotic relationship.
On top of that, you have a whole range of religious professionals (fortune tellers, funeral wailers, daoist masters, Chinese medical doctors, qigong teachers, monks and nuns) whose existence is basically parasitic--they take from society, while providing nothing worthwhile in return (unless you believe their metaphysical claims).
And then there are religious institutions, small and large. Some temples originally had a neighborhood or clan based identity. As people became more mobile, they lost a lot of these connections, and either declined, or became run in more of an entrepreneurial spirit. Religious specialists who would formerly have worked for an institution, now run them for their own benefit. At the extreme end of this we see the truly large religious networks (both "Buddhist" and "Daoist," and some difficult to classify, like Yiguandao or Master Qinghai) which are sufficiently gung-ho to go out and recruit people. Most of these are taking advantage of a fundamental weakness of local religious identity, which makes folk religionists easy prey for other, better organized groups intent on poaching adherents. Lest we suffer from an elevated notion of religion, I note that many such groups have connections with organized crime and/or local political parties.
A fourth level would be that of society itself, as reflected in such things as holidays and political customs (notice how nobody objects to children being forced to study Confucius--try THAT in Alabama!).
"Then how do you explain Rasputin's mesmerism and inhuman vitality? Stalin's army of human-ape hybrid soldiers? The use of lasers during the battles on Damansky Island in 1969? The undisputed fact that creatures not of this earth have infiltrated the Volgograd region so completely that they are effectively in control? And I'd be very interested in hearing what you have to say about the Black Volga." --Red Ned Lynch, responding to "scientific" explanations of the 1908 Tunguska event in the Talkbacks of Ain't It Cool News
