When it comes to longevity, everyone agrees that it is related to a good attitude, regular work and rest time, and a healthy diet, and in fact, it does have a lot to do. However, some people have their own longevity secrets, this prime minister is like this, he can be said to be the longest-lived prime minister in China, his wife is more than the emperor's harem, he is greedy for pleasure, but he lived for 104 years, and the longevity secret is only 3 words.

In 256, Zhang Cang was born in Yuanyang County, white and fat when he was born, and his father saw the great joy in his heart, which must be a healthy child. He liked to read since he was a child, and all kinds of genres were involved, so he was brilliant, and during the Qin Dynasty, he served as a royal historian, but he escaped because of a crime, and after returning to his hometown, he had nothing to do every day, and he always wanted to do a big cause.
When Liu Bang attacked the city, he passed by his hometown, Zhang Cang followed Liu Bang as a guest, and then he was sentenced to death for committing a crime, before the execution, he also knew that he was doomed, and wanted to die a little more heroically, so he dragged his clothes. At that time, Wang Ling was also present, and he was very surprised when he saw it, why a tall and strong person had skin as white and tender as a baby.
Wang Ling felt that this person should not be simple, so he pleaded with Liu Bang to let him go, and Liu Bang also paid attention to him. Later, Zhang Cang made great contributions while following Liu Bang, so he ordered him to be the acting minister of state. Years of work experience gave him a high degree of qualification, coupled with his proficiency in calculations, music laws and calendars, the Nine Chapters of Arithmetic was corrected by him, so after the death of the prime minister in 176, everyone recommended him as the successor prime minister.
After Zhang Cang became the prime minister for more than ten years, he was demoted because he was misunderstood by the emperor, and then because the candidate recommended by Zhang Cang used means to seek his own selfish interests after taking office, the emperor had already had an opinion on Zhang Cang, so he used this matter to accuse him. Zhang Cang was also depressed and seriously ill because of this matter, and he knew that his current situation was very dangerous, so he simply returned to his hometown.
Zhang Cang was in a good mood after returning home, eating and drinking every day, his illness was also better, he also liked to take concubines, there were more than a hundred, although the emperor's harem had three thousand beautiful women, but in fact there were only a few dozen people, so Zhang Cang's wife was more than the emperor. And he also has a very special habit, no matter how much he pampers his wife, as long as he is pregnant, he will no longer be close.
In his old age, Zhang Cang's body was not as good as before, and his teeth were also lost, sparse and sparse, and he could not eat. Zhang Cang ate liquid food all day and was very bored, so he changed his taste and found a lot of nursing mothers. Zhang Cang's body is still tough since eating breast milk, much better than eating liquid food, so he has been eating this.
Zhang Cang was very hardworking when he was prime minister, in addition to handling political affairs, he also studied the calendar, which he was interested in, and he did not love sports and had irregular schedules, but he lived to an advanced age of 104 years, which made people puzzled. Therefore, many people have asked him about the secret of longevity, and he tells anyone that it is 3 three words "eat breast milk".
This answer is obviously incredible, but in the late Qing Dynasty, there was a large family of shaoye, who drank breast milk until the age of seven before weaning, but in the war years, he lived to the age of 97, which can be said to be quite long-lived, so drinking breast milk should be able to play some longevity.
