In which dynasty did the flower armor begin?

Sixty flower jiazi is a combination of heavenly stems and earthy branches, commonly known as "sixty flower jiazi". Flower armor: refers to 60 years old. Named after heavenly stems and earthly branches's intricate name. Ji Yougong's Chronicle of Tang Poetry (Volume 66): "(Zhao Mu) Li Changji, a middle school student in Xian Tong, is a short song. He said to the wine,' Move sixty flowers by hand and the cycle will fall like a pearl.'

As for "being buried alive even at the age of 60", it was produced in the Middle Ages because of the lack of living materials. In order to ensure the continuity of the family, cruel abandonment of the old has occurred in different periods all over the world, but the manifestations are different. The oldest example is the archaeological evidence of Beijingers 500,000-600,000 years ago, which shows that in the period of food shortage, Beijingers will kill their elderly individuals as food. More than 100 years ago, Darwin discovered a tribe that abandoned the elderly when he visited Tierra del Fuego. The primitive tribes who accepted Darwin lived in caves or tree nests like cavemen in Beijing. They didn't wear any clothes. It is said that human beings began to wear clothes 70 thousand years ago. This African tribe is many years behind their ancestors. What surprised Darwin most was that the tribe always put the old women into the forest to starve to death. Asked why they did this, their chief replied that women have children. Since older women can't have children, why eat for nothing? Although the answer is naked, it is true and concise. In that extremely scarce environment, the survival strategy pursued by human beings is so cruel. It is better to raise children with limited food than to support the elderly, because children grow up to be productive and can produce more food. However, if food is too scarce to raise children, people in that environment will choose to eat children. First of all, killing children saves food for young people. Secondly, children can be used as food to supplement insufficient production.

Japan is a small island with limited energy. For the survival of the people, abandoning the old customs continued until the middle of last century. That's why Japanese director Takesuke Muxia made a film "Song of Naraku Mountain" on 1958, with the theme of abandoning the elderly in a barren mountain village. It is about an old man in his sixties who will be carried to the mountains by his son and left there to die and starve to death. With the development of modernization in Japan, this custom disappeared. Local folk songs illustrate this historical fact.

As early as China 1936, Ma Changshou, a scholar of the Republic of China, published the article "The Origin and Reproduction of Ancient Flowers in China". This should be the earliest known article about China's "abandoning old customs". Mr. Ma Changshou mentioned in his paper that there is a "living" tomb in Hexi Village, leping town, Xiyang County, Jinzhong City. Living Tibetan is also called Sixty Flowers and Jia Tombs. Mr. Ma's "seclusion" and "model grave" are so similar, even the legendary "Sixty Flowers". Yan Yong, director of Yantai Museum, mentioned in his paper that "in the early Ming Dynasty, in order to solve the problem of small land and large population in Jiaodong Peninsula, it is undeniable that there were a large number of immigrants from Shaanxi and other places". Looking at the papers of Director Yan Yong and Mr. Ma Changshou together, the "Shengzang" in Shaanxi and the "Zimu Tomb" in Shandong should be of the same origin. As Shanxi immigrants moved into Shandong Jiaodong Peninsula, they brought their unique burial custom-"living in Tibet" to Jiaodong Peninsula.
