In the long history of ancient China's Haohan, the role of Cheng Xiang has always played a pivotal role, and the celebrities who have come out of this post are all famous writers, Cao Cao, the tyrant of the chaotic world, Zhuge Liang, who bowed down to death and died, Wang Dan, the holy minister of the Master of All Things, Yang Guozhong, who sent troops to fight against An Lushan, and so on, there are loyal ministers and filial pieties, and there are also adulterous males and courtiers. The minister we are talking about today, although not a famous person, also has his own legendary life, from a prisoner who was almost executed to a high position in the position of a great power; he was born in the fifty-first year of King Zhaoxiang of Qin (256 BC) and died in the fifth year of the Han Jing Emperor (152 BC), spanning the middle of two centuries, he was the longest-lived cheng xiang after the Qin and Han dynasties, under the guidance of the great thinker Xun Zi, the protégé Jia Yi, he was the chancellor Zhang Cang of the Western Han Dynasty.

<h1>From Qin to Han</h1>
Zhang Cang is a native of Yangwu County, Qindi, who once studied with the great thinker Xunzi and has been good at reading, jingyin, and xiao law since childhood. He once worked as the imperial history of the Qin Dynasty, was responsible for managing the documents and archives in the palace, and it was also a pleasure to combine work and hobbies. However, the good times did not last long, Zhang Cang was worried about being punished because of the crime, and ran home as soon as he slipped a cigarette. Later, when Liu Bang grabbed the territory and passed by Zhang Cang's hometown of Yangwu, Zhang Cang offered himself to follow Liu Bang as a guest.
<h1>To live in the dead</h1>
In the process of following Liu Bang's attack on the city, it was unfortunate that Zhang Cang once committed a major crime and was sentenced to death. People had all been pulled to the execution ground, their shirts were taken off, and they were lying on the instruments of torture, and they were about to be executed. At this moment of a thousand guns, he happened to be seen by the passing general Wang Ling, who was a red man around Liu Bang, and liu Bang's choice of wang ling, which Liu Bang said to Lü Hou before his death, was also listed. When Wang Ling looked at Zhang Cang, who was tall and had fair and fat skin, he felt that this person looked particularly good, calling him "Meishi", not an ordinary person. (The author speculates: it should be that most of the people at that time were black and thin, so Zhang Cang's appearance was more special, which attracted the attention of Wang Ling.) Wang Ling quickly stopped the knife and axe hand to suspend the execution, and ran to liu Bang to intercede, and Liu Bang exempted Zhang Cang from the death penalty, and Zhang Cang was able to avoid a disaster.
<h1>Added officers to the knighthood</h1>
Zhang Cang followed Liu Bang, the Duke of Pei, to Liu Bang, the King of Han, and finally waited for the opportunity. Chen Yu was dissatisfied with his former friendship with Zhang Er as the king, and he himself was only made a marquis by Xiang Yu, so he joined forces with Tian Rong, the king of Qi, to defeat Zhang Er, the king of Changshan. Zhang Er ran to join Liu Bang, the King of Han, and Liu Bang appointed Zhang Cang as the commander of Changshan Commandery to accompany Han Xin in attacking Chen Yu, and Zhang Cang made a great contribution and captured Chen Yu. Therefore, Liu Bang also appointed Zhang Cang as the acting minister of state, responsible for guarding against enemies on the border. When the Yan king Zang Di plotted a rebellion, Zhang Cang followed Gao Zu to attack Zang Di as a state minister, and made great merits, so in mid-201 BC he was given the title of Marquis of Beiping, with 1,200 households. After that, Zhang Cang successively served as a planner, chief planner, and imperial historian, and his career was smooth.
<h1>Promotion phase</h1>
In 176 BC, Xiang Xiang died, and Zhang Cang took the place of Xiang Xiang. This year, Zhang Cang was already eighty years old, and he had been sitting in this position for fifteen years. During his tenure, he proposed and formulated a relatively complete set of theories on weights and measures, and directly applied the results of arithmetic research to the national economy and people's livelihood; revised the musical laws and calendars. It fully demonstrates his erudite and academic demeanor.
However, fifteen years later, Zhang Cang's political career encountered another obstacle. Emperor Gongsun of the State of Lu said that he was watching the stars at night, and sensed that there would soon be a auspicious omen of the apparition of the Yellow Dragon, so Emperor Wen of Han sent Zhang Cang to check it out. As a result, Zhang Cang neither believed in the apparition of the Yellow Dragon nor took any action. However, Huang Longguo really appeared, Zhang Cang was immediately degraded, and caught up with a person that Zhang Cang had recommended to use his power for personal gain, zhang Cang was once again led, and had to rely on illness to return to his hometown.
<h1>Longevity secret</h1>
After Zhang Cang returned to his hometown, he lived for another five years, until he died at the age of 104. The reason why he can live so long is, of course, inseparable from his many hobbies. There is nothing to look at the sky, study astronomy; read books, see the ancient sages, understand the state of life; play the flute and make music, cultivate sentiments. It can be said that Zhang Cang can be a model of health for me and others.
In addition to these hobbies, according to legend, Zhang Cang also has two longevity secrets:
1. Do not drink alcohol or eat spicy and irritating foods;
2. "History; In the biography of Zhang ChengXiang, it is recorded: "After the release of the cangzhi, the old man, toothless in the mouth, feeding on milk, the woman is a nursing mother." The number of wives and concubines is in the hundreds, and those who taste pregnancy are not lucky. That is to say, after Zhang Cang was deposed, he was so old that he had no teeth, drank human milk to supplement nutrition, and had hundreds of wives and concubines, but once he became pregnant, he was no longer lucky.
Zhang Cang's legendary life, we only have the envy of the share, but his wide range of hobbies, self-cultivation skills we can still learn from one or two. Of course, drinking human milk is still not suitable for promotion.
