Through the date and time of death of the deceased, we can calculate which of the six ways fell after death.

According to relevant Buddhist classics, judging which way the deceased took after death depends on which part of the body has the highest temperature. If the rest of your body is cold and only the top of your head is hot, you will go to the pure land of Buddha; If the forehead is hot alone, it is heaven; If the heart is alone, it is humane; If the abdomen is hot alone, it will go to the ghost road; If the knee is hot alone, go to the animal path; If the soles of your feet are hot, go to hell. There is a son who is easy to remember: "The holy eyes are born, the human heart is evil, the knees of animals are off, and the feet of hell are out."

Many people in the world died at the same time on the same day, so it is impossible for different industries to go to the same place. So calculating the time of death is not as good as the law.
