Can a fortune teller work out when he will die?

Can be calculated, in ancient times, must be calculated. For example, how old was Shou Yuan, who died in sunny and cloudy days, was ill for a few days before his death, and died in sunny and rainy days. All these should be clearly written. Don't write this. People think you can't tell fortune. Moreover, some masters can decide what disease he will die of, when he dies, what color the coffin is when he dies, what wood it is made of, which direction the funeral will go, how many male and female guests died, which Shan Ye in Long Mai and so on. Anyway, the more detailed he writes, the more learned he is. It is the fortune teller who can make detailed decisions. As for accuracy, is it inaccurate? It doesn't matter. If a person wants this statement, the fortune teller must give him a statement first. Right or wrong is another matter. Anyway, death tells no tales. Someone wants to take his approval letter for life to verify it. I'm afraid the master passed away several years ago.
