Buddhism has a way of getting pulled into syncretistic practices so you might go to a famous Buddhist temple and find there is a room in the back where there is a Buddha statue which is inhabited by a fox spirit (see the link in my other post) which is believed to be more effective to ask things from than the other statues. When Christianity was outlawed in Japan, Christians prayed to statues of Cannon because Cannon is a goddess of compassion a lot like Mary.

You could make the case for Chinese experiencing a spiritual vacuum like this: not long ago individuals were living in rural areas where they had folk religion in addition to officially approved Buddhism-Taoism-Confucianism. When they move to city they are cut off for these roots and could be looking for something.

My son had a Chinese friend who had bad relations with his parents, particularly his friend would ridicule his mother for growing up in a rural village where she learned that mental illness is caused by demon possession and such.
