Why can't the same thing be repeated? What if I find several different people and the divination results are all the same?

Because there is no basis for divination, it is difficult to know where it has gone by throwing it casually, so it is impossible to occupy several divinations in the same place at the same time. In addition, it is very likely that the first time is different from the second and third times. If it's different, and Mr. Wang can't explain it, it's asking for trouble, so Mr. Wang is not allowed to possess it again.
