What does the fortune teller mean when he says he can't figure out the time?

Sometimes your constellation is smart enough to form a constellation full of yin or yang, and some gentlemen don't look at it. (at least I don't watch)

Others have seen it, but it's not good, so naturally I won't say it (what if I'm beaten? I can solve it myself, but it's no use talking if I can't solve it. )

There is another kind, that is, knowing other information, such as knowing that you are a caesarean section, then this character is useless. Naturally, I can't figure it out.
