A cycle, ancient 12 earthly branch 10 days, takes 60 as a cycle and has six nails, namely: Jiazi, JOE, Shen Jia, Wu Jia, Chen Jia and Jia Yin. This cycle, the ancients called it Zhou Jia, also known as "Huajia". In ancient times, this method was used to mark the year, and 60 years went on like this. Later, he was called 60 years old with "flower armor". Related idioms are "the year has passed" and "the year has passed".
Zhao Mu, a poet in the Tang Dynasty, wrote in Duijiu: "Sixty flowers are like pearls in the hand". Fan Chengda wrote in "Wu Bing's New Book": "I wish you a beautiful wife and thank you for your advice." The flower armor here refers to 60 Jia Zi, also called "flower armor". In the Qing Dynasty, Confucius wrote in Peach Blossom Fan: "On this day of the year, ask Heaven what flowers you have eaten." The "flower" here refers to the year, month and era.
At the age of seventy:
Gu Xi is also known as "Gu Xi" and "life is seventy years old", which means that a person lives to 70 years old. A person is considered very old when he lives to 70 years old, especially in ancient times when the average life expectancy is not high. Therefore, the ancients thought that few people lived to 70 years old, so they called 70 years old "seventy years old."
The most classic poem about ancient times is Qujiang written by Du Fu, a "poet saint": "Wine and debts are everywhere, and life is seventy years old", which means that it is an ordinary trivial matter that people can live to seventy years old, which is rare in ancient times.
In the Ming Dynasty, Tang Yin (Tang Bohu) wrote a poem "Seventy Words" for feeling that he had had a "rare life": "Life is seventy years old, and I am seventy years old. The first two years are young, and the last ten years are old. There were fifty years in between, and half of them passed overnight. I have been alive for only twenty-five years, and I have suffered many troubles. "
In ancient times, the "old and rare" old people who lived to be over 70 years old and other scholars were great. And when they look back at the past at the age of seventy, if they have accomplished nothing, they will still be unable to help sighing and crying.
