What does it mean to look at flowers and tell fortune?

Recently, it is popular for colleagues to ask for fortune telling, and they believe it and spend a lot of money. Is fortune telling reasonable?

If you believe, you have it; No, you do.

In fact, our family also discussed this issue yesterday, and summed it up as fortune telling now, which can tell your past and present, but rarely tell your future ... If you look at it from the probability, can you assume that a blind cat catches a dead mouse? =.=

As the old saying goes: secrets cannot be revealed; Sometimes you need to hit it at once, don't force it all the time.
