What does divination need?

Tarot cards and flower buds are more useful. If you use flowers for divination, you need a professional teacher to teach you. Tarot cards can be taught by themselves. I suggest you buy tarot cards, which are very detailed. They are sold in many places, about forty yuan. It's harder to find than a compass or something. I once saw someone using an English divination stick on TV. This is very clever, but it seems that he must go to England specially. This is a very traditional divination.
