【Han Dynasty Story 25, Original Work of Little Buddha Saying History, Please Do Not Reprint】
Liu Bang was one of the few mixed-up emperors in Chinese history, and as a teenager, instead of working hard like his father and brother, he thought all the time that he could turn to a capable person, such as Xin Lingjun, as his protégé. However, Liu Bang failed to do so, and only returned to his hometown after the original Xinling Jun's disciple Zhang Er (who later fought with Liu Bang and was named the King of Zhao) after being a short-term disciple.
Liu Bang, who went out for a while, was more and more reluctant to follow the old path of his father and brother, and he did nothing in the township all day, and then he became the pavilion chief of the Surabaya Pavilion, and Liu Bang, who was not married, always fought with some women after work. Little Buddha remembered that in a book he had read before, "Liu Bang", it was mentioned that most of these women were widows. Some people will ask, Liu Bang asked what would he do to hook up with widows instead of good family women? At that time, Liu Bang was a jerk, the women of the good family looked down on him, and at that time, the Qin Dynasty recruited farmers to build the Great Wall and the palace, and many men never had the opportunity to come back after leaving their hometowns, and the wives of the family could only be widows, and the base number of widows was quite large.
One of the women Liu Bang hooked up with was surnamed Cao (some people say that this woman with the surname Cao should be Cao Widow), and the two gave birth to a child before Lü Yan officially became Liu Bang's wife, and this child was Liu Bang's eldest son, Liu Fei, "Liu Fei, the Prince of Qi, gaozu Changshu male also." His maternal grandmother was also known as the Cao clan".
Although Liu Fei was Liu Bang's eldest son, he basically did not raise Liu Bang when he was young, and because he was not born to his wife Lü Yan, Liu Fei had no chance to become Liu Bang's heir. However, Liu Bang was okay with his eldest son, and after his departure, he took Liu Fei to his side, and after becoming emperor, he may feel ashamed of his eldest son, so on the 20th birthday of his eldest son, Liu Bang gave his son a big birthday gift - taking the place where the Duke of Qi Huan had been in the limelight as Liu Fei's fiefdom, and sealing Liu Fei as the King of Qi. How big is Liu Fei's fiefdom? According to historical records, there were a total of seventy cities, and he was the largest of the many princes at that time, "eating seventy cities, all the people who can speak together are given to the king of Qi", and sent his old friend Cao San to the State of Qi as the minister of state, hoping that Cao San would teach his eldest son to govern the place well.
Liu Bang may not have thought that his eldest son was almost killed by his wife.
Liu Bang died in the twelfth year of Han Gaozu's reign, and the crown prince Liu Ying took the throne, and two years later, Liu Fei, as a local prince, went to Chang'an to pay homage to his emperor's brother. Liu Ying was not as strong as his mother, believing that although he had become emperor, his brother was still his brother, so he arranged a family banquet in the palace and let his brother sit on his own hands. Lü Hou was very dissatisfied with this, so he signaled his attendants to poison Liu Fei with poisoned wine. Liu Fei also did not think that his mother-in-law would be single to himself, get up and take the poisonous wine to drink, Liu Ying seemed to realize that his mother was wrong, but also to drink the same wine as his brother, Lü Hou hurriedly overturned the wine glass in his son's hand, Liu Fei also realized the abnormality of Lü Hou's behavior, so he said that he was invincible, and he did not drink the poisonous wine and retreated.
After Liu Fei left the palace, he told his courtiers about the family banquet, believing that Lü Hou would have to get rid of himself sooner or later. Fortunately, Liu Fei's attendants were clever, so they gave Liu Fei a life-saving strategy: "The empress dowager has only filial piety and Princess Lu Yuan. The present king has more than seventy cities, and the princess is a number of cities. Wang Cheng took a county to be the empress dowager, as the princess Tang Muyi, the empress dowager will be happy, and the king will be worry-free. Therefore, the King of Qi was shangchengyang County, and the princess was honored as empress dowager", in the current parlance, he gave the chengyang county in his fiefdom to his sister as Tang Muyi (referring to the private estate of the monarch, empress, princess, etc. who collected taxes), and treated his sister as empress dowager (empress dowager Qi, it is reasonable to say that empress dowager Qi must be the biological mother of king Qi, that is, Cao, Liu Fei really fought to save his life).
Lü Hou was very satisfied with Liu Fei's approach, so he did not have the intention of killing again and let him return to the State of Qi. A few years later, Liu Fei died. Some people say that Liu Fei died at a young age, and it is not excluded that he has long been worried that Lü Hou will attack him and end up depressed.
