What are the disadvantages of helping others?

Brother Luck, I think if the leak can really be established, it will prove that your calculation is really accurate, and you are not making it up.

Personally, I think you should not help strangers casually in the future. If you want to count, you should charge a nominal fee to do good deeds. I have seen in Tianya before why some famous fortune tellers or geomancers charge high fees because they need to use the money to do good deeds and accumulate virtue for themselves and others.

The ancient emperors were surrounded by one or two people who were proficient in the Book of Changes. But they often sacrificed to the gods to do charity chanting and advised the emperor to do the same. I think these actions are reasonable.

Anyway, I don't think you should do it for strangers online for the time being. If you have practiced before, I don't think it is necessary to practice now. I think what you said is very accurate.
