Can't anyone just touch gold, titanium and gold?

Generally speaking, if you buy a titanium crystal amulet to ward off evil spirits, the clerk will have degaussing action. In this way, when the titanium crystal is worn on you, it will absorb your energy first, and after a period of time, it will be consistent with your magnetic field and form resonance to strengthen your magnetic field.

If someone touches it, it doesn't matter for a short time, but it's better to have clean hands. That person is upright.

It may change the magnetic field of titanium crystal for a long time, and it needs to be degaussed and worn again, which is more troublesome.
