What is the principle of fortune telling?

There are many principles for fortune tellers to tell people's fortune. As the saying goes, one of them is, don't tell lies, don't tell the truth completely, don't ask, don't tell at all. Assuming that this person does not ask about life and death, it will not be such a thing to provoke people's sensitive nerves, so as not to be misunderstood as scary, but to cheat by changing their lives. Suppose this person asks, please ask Mr. Wang to calculate the life span. Fortune tellers can't refuse to count, so they should use the principle of not telling the truth. In the fortune teller's view, life is to find a way to live, not to die, so he has no right to know his own death. Therefore, fortune tellers only say half, not the other half, that is, the life span can be directly said, and the date of death can never be said. This sounds contradictory. In fact, the years of life are not the date of death. According to the previous fortune-telling regulations, there are three periods in life, that is, there is a ditch after crossing the ridge and a pit after crossing the ditch. This is not destined to stop. This involves many factors, such as personal morality, geomantic omen, good and evil, etc. It is not the jurisdiction of fortune tellers, so in the end, fortune tellers will not tell lies. Suppose this person asks, do you think I will commit suicide? Fortune tellers have a set of opinions, so-called self-punishment, self-death. Fortune tellers can generally tell, and they also advise people to fear life and attach importance to family ties. It is better to persuade people to die than to persuade people to live. Heaven gives birth to virtue. They advise people to accumulate virtue, build bridges and roads, fill pits and cross borders, and so on. Life and death are reserved for people. As for those who come to kick the stalls and the gazebo, they must be accurately counted as dead. Such an uncertain lie can never be told. At most, they will say: thank you for not accepting fortune telling, please ask someone else for wisdom.
