Many people are not particularly familiar with the existence of Cao Shi, because she did not occupy a high position in history and died young. How Cao Shi died has always been controversial. Some people think it's because of her medical history, while others think it's because of assassination. About her death, we still need to conduct in-depth analysis and discussion.

First, Cao Zhi's life records that Cao Zhi is a fellow countryman of Liu Bang and a rich man. Before Liu Bang married his wife, Lv Zhi, she had been with Cao Shi, so Cao Shi was not Liu Bang's wife, but only a lover, but she gave birth to her first son, Liu Fei.

The arrival of Liu Fei also directly affected the status of Cao Shi. The sons of Cao Shi and Liu Bang are concubines at most, and have no right to inherit the throne, so Liu Bang finally named Liu Fei King of Qi. Because Cao Shi and Liu Fei have no formal birthright, if they want to compete for imperial power, they will be a thorn in many people's side.

Second, the relationship between Cao Zhi and Lv Zhi Through the records in the history books, we can know that Cao Zhi was still very young when he died. What happened before she died? In fact, everyone can think that Cao Shi is Liu Bang's lover, Lv Zhi is Liu Bang's wife, and Lv Zhi is not a compassionate person. So, how can she tolerate Liu Bang's lover?

Third, what about Cao? What happened to Cao? In fact, the history books did not record the cause of Cao Shi's death, while other books did. In fact, I think he may have died of assassination, and the mastermind was Liu Bang's wife Lv Zhi. First of all, after Liu Bang and Lv Zhi got married, Liu Bang was idle at that time, and Lv Zhi led the whole family to work together to make a living.

So in this respect, she is a person who can manage the family diligently. As such a woman, how can she share her hard work after she and Liu Bang unified the country? Therefore, at this time, Cao Shi is the only one who can interfere with her most. Cao Shi's death also makes sense.

Secondly, Cao Shi's death may not be directly killed by Lv Zhi, but perhaps by some kind of non-proper relationship, because Lv Zhi has taken Liu Bang's favorite concubine and Mrs. Qi hostage for many times, and its cruelty can be imagined. Although historical records show that Liu Bang lost in a war, all his family members were captured. Cao, among them, was imprisoned. At this stage, they established a profound friendship.

Although Cao Shi is not particularly interested in imperial power, he still hopes that his son can make a difference. So I entrusted my son to Lv Zhi. Although Lv Zhi has no hostility to Cao Shi on the surface, she has long been obsessed with her son, because Liu Bang made Liu Fei king of Qi and gave him more than 50 cities to make up for Cao Shi's mother and son. Liu Fei visited his younger brother Liu Ying, and Lv Hou almost poisoned Cao Shi's son with poison. Because Liu Ying almost drank the poisoned wine, Liu Fei's life was saved.

In fact, it is not difficult to imagine that the former good sisters are good sisters who share weal and woe. Lv Hou once promised that Cao Shi would take good care of her son Liu Fei, but in the end she broke her oath and almost killed her. It is not hard to imagine that if the oath between good sisters is broken, what else can't be done? So Cao Shi's assassination is very reasonable.
