According to the Han bamboo slips in Wuwei, China officially proposed to respect the elderly and provide for the elderly early.

There are 1959 royal slips and 10 wooden slips of the king's staff unearthed from the Han tomb of Mozizi 18 in Wuwei, which is called "Ten Slips of the King's Staff" in history. Jane is 23.2 ~ 23.3 cm long and about 1 cm wide. In the fifteenth year of Yongping in the Eastern Han Dynasty (AD 72), young people received the king's scepter, which recorded the imperial edicts of the second year of the Western Han Dynasty (BC 72) and the second year of the capital (BC 3 1 year). Bamboo slips were untidy when unearthed, and the arrangement order of 10 bamboo slips was controversial. 198 1 year, Wuwei County Cultural Relics Management Committee collected 26 pieces of imperial edicts, which were also said to have been unearthed in the Han Tomb of Mozuizi. Each piece was 23.2 ~ 23.7 cm long and 0.9 ~ 1. 1 cm wide, with serial numbers on the back. Look at "1" to "27th" today. The above imperial edicts are related to the special care of the widowed and disabled elderly, and are important materials for studying the pension system in Han Dynasty. The Bamboo Slips of the King's Staff unearthed twice are rich in content and clear in records, including clear orders to respect the elderly, clear provisions to give the king's staff when he is old, and specific laws and regulations to help the widowed and disabled. These orders and regulations, first, improve the social status of the elderly; The second is to reduce the punishment for the old, weak, sick and disabled; The third is to exempt them from corvee tax. During the Western Han Dynasty, the state carried out three major changes in the system of supporting the elderly, namely, exempting the old and the young in Hui Di's period, giving the king a scepter in Xuan Di's period and relaxing it in the period of Emperor Wu of the Han Dynasty. However, the last two of these three changes are not clearly recorded in the history books. The discovery of Ten Bamboo Slips of the King's Staff, especially the Imperial Bamboo Slips of the King's Staff, fills this gap for us. For thousands of years, many questions about "sending a king's scepter at the age of 70" have finally been clarified.
