What does the fortune teller mean by longevity?

Hello, Uncle Dou's family is at your service at any time. Longevity means that you will die when you are young, which is also commonly known as premature death. Shou Yuan is short. Of course, modern fortune tellers rarely mention the problem of premature death to others. This is immoral and will increase the psychological burden of the subjects. Generally speaking, there are many disasters. Fortune-telling is basically not the length of life, because the length of life mainly depends on the cause and effect of previous lives and the merits and demerits of this life. What good and evil things have you done, including your living habits, luck, health, etc. If Shou Yuan can predict, wouldn't people with the same eight characters born on the same day of the same year die on the same day?
