Chinese/Taoist Spirit-Mediums are called Tang-Ki, literally "child diviners". Chinese Spirit-Mediumship is calling upon a spiritual being, or Deity to temporarily possess a human body.
In such a state, the Tang-Ki becomes the personification of the Deity and mediates between the human and spiritual worlds. Human beings can then consult the spirits/deities, seeking advice as well as solutions to human problems.
In Western Countries, many folks who consider themselves as Taoists or interested in Taoism only have the chance to read the Book "Tao Te Ching".
This Documentary on Tang-Ki Worship will be able to let You expose deeper into Religious Taoism Practice by the Chinese Communities.
