High score reward: solving the problem of too accurate fortune telling

According to a fortune teller I know, there is a certain pattern in what happens. Those fortune-tellers who learn Zhouyi well can calculate what happened according to the rules (including the situation at home), and those who don't learn well can only know it by asking your eight characters.

I guess you met a master.

But for the future, fortune tellers can only estimate the direction of development. Some fortune tellers will tell you exactly what happened in order to make people believe. Most fortune tellers are more susceptible to hints, and some things will develop according to what they say.
