Because it is the depth of winter now, but there are west winds and north winds, and there are east and south winds... If it is spring in October, I have already prepared for it. ? ”
From this short dialogue, we can see that Cao Cao’s men are not without capable people. Cao Cao is indeed experienced in the battlefield and is good at using troops. He is still very considerate.
< p>One of the questions is, why did Cao Cao say "Little Spring in October"? There are two explanations for the saying that October is Little Spring in the lunar calendar.The weather is not very cold yet. It has a feeling of warmth like early spring, so it is called Xiaochun, also known as Xiaoyangchun. Volume 37 of Chen Yuanliang's "Sui Guang Ji" quotes "Ji Xue Ji" as saying: "The sun of the winter moon brings all things back."
Because it is as warm as spring, it is called Xiaochun, also known as Xiaoyangchun. "Ouyang Xiu's collection of essays has this poem: "In the early spring of October, the plum blossoms are blooming, and the red stove bookstore is newly decorated. "
The second chapter of "Tian" in Xie Zhaozhe's "Wuzazu" of the Ming Dynasty said: "It is the air of heaven and earth. It is cold in April and warm in October. There are peach and plum blossoms, which is commonly known as Xiaoyangchun." "The second explanation is: The Qin Dynasty used the Zhuanxu calendar, with October (the month of Jianhai) as the first month of the year, that is, the beginning of the year.?
Zhang Cangxu in the early Han Dynasty According to the law, because Liu Bang came to Bashang in the tenth month of the lunar calendar, the tenth month of the Qin Dynasty was still used as the first month of the year. It was not until the first year of Taichu, Emperor Wu of the Han Dynasty, that the Taichu calendar was used, and the first month of the year was changed from tenth month to the first month.
Because people were accustomed to seeing spring as the beginning of the year, the tenth month of the year was called Xiaochun, also known as Xiaoyangchun. By the end of the Han Dynasty and the Three Kingdoms period, the first month of the year had been changed to the first month. People also have the habit of calling October "Little Spring".
