Some people say that fortune tellers are bad for their families. Is it true?/You don't say.

There is no such thing, so there are only two sources of similar statements. The first one is a charlatan who wants to improve his social status.

The second kind is Buddhist laymen.

Real fortune-telling has nothing to do with what family is good, five evils and three deficiencies, and what outdoor machine to use.

As for why Buddhist laymen preach this statement. Please show me other answers. I have answered them many times.

This is also the reason why other people who study Yi-ology don't like Buddhism, except those who believe in Buddhism, but they have never really studied Buddhism and have only been fooled by a few brainwashing words.

She should concentrate on Taoism. Although Shi Tian Daoism introduced Yi-ology, it is interesting to study Yi-ology in China all day.
