The age of fortune telling _ the age of fortune telling
"73, 84 is a hurdle for life and death" comes from the folk saying that "73-year-old, 84-year-old, the king of hell doesn't deserve it", which is an old saying. Without saints, you can't live. In fact, this proverb has no scientific basis, but it has an extraordinary origin.
In fact, this has something to do with the death of two ancient saints in China, Confucius and Mencius. Confucius was born in 55 1 year BC and died in 479 BC. He is seventy-two years old and seventy-three years old in name only.
Mencius was born in 372 BC and died in 289 BC. He is eighty-three years old and eighty-four years old in name only. Because the ancient people's ages were calculated in nominal years, Confucius died at the age of 73 and Mencius died at the age of 84, so there was a saying that "73 and 84 are a hurdle for life and death".
