The elderly are a group that cannot be ignored at any time in society. They are old and weak, unable to work, unable to create social wealth, and even have to be taken care of. Which dynasty's old people lived the happiest, old people and old people? After textual research, the care for the elderly in Han Dynasty is incredible. In the Han dynasty, from the emperor to the people, filial piety was required. The emperor's imperial edict stipulates that those who can't recruit old people without authorization, insult and scold the old people, the law will never show mercy and will "abandon their children" and be put to death. There used to be a curator of Yunyang Baishui Pavilion in Runan area, named Zhang Ao, who bullied the old man and dragged him to a temple, which had a very bad influence. Taishou and Tingwei don't know how to solve it. They made trouble with the emperor, and the emperor said, "You should abandon the city if you compete with the imperial edict." Zhang Ao was executed. According to the pension system of the Han Dynasty, an old man over 50 with good character who can lead everyone to do good deeds can hold the post of "three seniors"; Older people over 70 who have no personality problems can not only be on an equal footing with local officials; Old people over 80 "nourish aging, give a few sticks and eat porridge." The old people are exempt from corvee, and the court gives wine and meat subsidies every year. When meeting the emperor, the old man can "walk on the roadside", which is not even treated by the prince. Every autumn, the imperial court will conduct a census and hold a staff awarding ceremony for the elderly who meet the age requirements. "Mid-autumn moon, county and road are all in proportion to the people. At the age of 70, give them jade tablets and feed them porridge. Eighty, ninety, plus gifts. The jade stick is very long and decorated with pigeons. Pigeons, don't choke, want the old man not to choke. " This is recorded in detail in the Book of Rites of the Later Han Dynasty. The system of selecting officials in the Han Dynasty, "respecting filial piety and saving righteousness", seems to attach importance to the elderly today.
