Can Buddhists hire Yin and Yang teachers?

Strictly speaking, Buddhism does not advocate lottery, fortune telling and geomantic omen, nor does it believe in such things, especially geomantic omen. However, Buddhism is more of a convenient method. If some psychological problems can be solved, I think it is harmless, as long as it does not violate the purpose of Buddhism. Buddhism and fox spirits can't both be believed, and they are not at the same level. It's hard to say whether those immortals are qualified to listen to Buddhism. Just don't be too addicted to these things.
