There is a very profound movie in Japan, called "Kaeyama Festival Examination", which tells that in a poor mountain village in ancient Japan, there was a strange "custom", the old man would be sent to the mountain by his children to die as soon as he reached the age of 70, which was used to worship the mountain gods.
China is a country that pays great attention to filial piety, such a thing seems incredible today, but whether there was such a thing in ancient times, it is still impossible to verify, there is also a "crock pot grave" in the folk, the son will be 60 years old parents locked into the "crock pot", every day to send bowls of rice and bricks, until the grave is sealed and no longer asked.
According to the records of ancient corpses and books, the average life expectancy of men in the pre-Qin period was 35 years old, and the average life expectancy of women was 39 years; the average life expectancy of men in the Qin and Han Dynasties was 49 years old, and the average life expectancy of women was 52 years old.
In prehistoric tribes, men and women weave, self-sufficiency, but the elderly mean that there is no labor force, that is to say, the family needs to prepare one more person's food, the children of the elderly also have their own children, in ancient times, pay attention to more children and blessings, don't look at just adding more grain to the elderly, this will also become a burden for children, especially in the case of low grain production, the old man is completely burdensome for his children.
And at that time, longevity did not mean auspicious, so the "crock pot grave" appeared, and why did people say that it was "filial piety"? The reason is that the old man is old and cannot do anything, so that his children can worry about it, and the children have to go to the field to plant crops and take care of their children's rations.
In the long run, the patience of the children is worn out, it is very likely that the beating of the elderly, forced labor and other situations, these are filial acts, people criticize, it is better to send the 60-year-old to the hole dug in advance, send bowls of rice and a brick every day, after 365 days, the cave entrance will be blocked, meaning "pension to the end".
However, in the historical records, there are many figures over the age of 60, such as the Shang Dynasty's "Ancient LoyalIsts" Bigan lived to the age of 64, Bigan was still the hand of the Shang Dynasty emperor Emperor Xin; Jiang Ziya was 72 years old and fished in Weishui, and was later reused, becoming the founding father of the Zhou Dynasty, and then fengQi jianguo, living to the age of 139.
If it is said that Bigan was born in the royal family and suffered differently from others, then Jiang Ziya was unknown until the age of 72, just a commoner, if he was sent to the cave by his son, probably the history would have changed completely, and it means that the "crock pot grave" did not exist or almost did not exist in this era.
The Zhou Dynasty paid the most attention to "etiquette", respected the elders, honored parents, and perfected the etiquette system, and later in the Spring and Autumn And Warring States period, academic controversy, health and medical skills were developed, the founder of Confucianism Confucius lived to the age of 73, Mencius lived to the age of 84, and supporting parents also became a traditional Chinese virtue.
