The problem of the crystal pendulum sold by Taobao

Actually, the price is not very important. Taobao also bought twenty or thirty pendulums. In fact, the pendulum still depends on personal thoughts and spiritual strength. If you don't have enough creativity, even if you buy hundreds or even thousands, it's useless.

If you want pure crystal, buy one with cotton wool or borneol. You can identify yourself when you get it. The simple thing is that the crystal can reflect colorful light to the light, and then try the temperature. Crystal has a cold feeling. If you are not afraid, scratch it with gravel, and the crystal will not have any traces.
