Question, which of the following are superstitious activities:

Only the first one is not superstition. The rest are superstitious activities.

A fan doesn't understand the truth, but a letter believes and relies on it. Denying the truth without knowing it is also called superstition.

The first one is not superstition. It is right for families to cross over for the dead. But the effect of crossing depends on the accomplishment of the people who do things and the sincerity of their families. You can also release more people or recite Buddhist scriptures and return your merits to the dead. However, all merits are returned to the deceased, and the deceased can only get one-seventh of the merits. The rest is the author's.

The second question is about witches. If witches are used by ghosts with magical powers, there will be some accuracy. But what's the use? It's no use. No matter how accurate a fortune teller is, it is better to correct his behavior and change his destiny. All good and bad are the result of behavior. So it's superstition.

The third medicine may be a folk prescription. If it's something, it might be useful. But what can a witch cultivate?

Four, five, six is complete nonsense.
