We know that human milk has extremely high nutritional value, and it is no exaggeration to say that it is human milk and mother's blood. Therefore, it is more nutritious for newborns to drink breast milk than milk powder bought in other markets, but some sick mothers are not suitable for breastfeeding their children. Other normal mothers suggest that it is better to breastfeed their children. But do you know that there was a prime minister in history who lived on human milk after retirement and lived to 100 years old? This man is Zhang Cang. Zhang Cang is the prime minister. He committed a crime because of something, but narrowly escaped death. It's amazing to say that his white skin saved his life.

When Zhang Cang was executed, the executioner uncovered his clothes and found that his skin was unusually white and his figure was very plump and round, which was different from the people here. So, he quickly reported Zhang Cang's abnormality to the supervisor. The supervisor thought that Zhang Cang was not an ordinary person, so he let him go and he survived. Later, Zhang became prime minister and held a high position. He did not forget the great kindness of supervising the country, so he always regarded him as his father. Later, Zhang Cang was scolded by the king. In his old age, he retired and returned to his hometown.

After Zhang Cang resigned and returned to his hometown, he devoted himself to studying the way of keeping in good health. Since then, he has been living on human milk, so he is in good health. He is old and has many wives and concubines. After he became pregnant, he had enough breast milk to drink, but he only drank the breast milk of his first pregnant wife and concubine. Maybe it's because he drank breast milk for a long time, maybe it's because he survived, so he must have good luck, leading to his long life of 100, which is rare even in today's rich material life.
