The experience of telling fortune by setting up a stall

How to persuade the stall computer to tell fortune?

Of course, a master can be accurate, there is no doubt about it. The main problem now is that the quality of fortune tellers is so low that some poor fortune tellers cheat money. For example, if you go to a fortune teller, you can directly report the date of birth, saying that you measured it for others, and then without saying a word, let the fortune teller measure previous events, such as academic qualifications, when you got married, when you were injured, when you broke money, how many children you had, and so on. If he is 90% correct, it shows that he has real skills. You can ask him to push future events, and then don't forget to give money to divination. I want to hire someone to do this, and this line is naturally clear. I have 2 yuan in my pocket to go to a fortune teller. Let him calculate how much money you have in your pocket. If it is accurate, it proves that you are capable. If accurate, at least not technically. If it is accurate, you can change the money in your pocket for 10 days in a row to find him. If it is accurate to 10 day, how do you explain it? I think this can be proved very simply, and there is no need to discuss and question all the time.
