Is it normal for fortune-tellers to ask for fortune-telling before fortune-telling?

Yes, I'm afraid I can't find it, because such a master can't calculate easily. Even if you find him, it may be a little "point" you want to calculate, and I won't tell you too thoroughly. Besides, you may pay a lot of money, and the effect is not great. It's also harmful for others to talk too much, because secrets can't be revealed, so don't hope for divination and dominate yourself! Good luck!
