If you make a ranking of the most ruthless women in ancient times, I believe that Lü Yan must be on the list after Han Gao, she made her love enemy into a "human" and tortured to death, and also found her son Liu Ying to appreciate her "masterpiece", then what deep hatred did she have with Qi Ji, let her use such cruel means to deal with Qi Ji? Is it really just jealousy?

Lu Lu
Lü Lu was also known as Han Gao Hou and Lü Hou, she was the original match of Liu Bang, the ancestor of Han Gao, when Lü Lu was not yet married to Liu Bang, Lü Lu's father Lü Gong was a rich merchant on the rich side, but at that time Liu Bang was just a pavilion chief of Surabaya Pavilion, the age difference between the two people was fifteen years old, which at that time could be said to be the wrong door, and Liu Bang also had an illegitimate son, but Lü Yan's father felt that Liu Bang was an extraordinary person in the future, so he married his eldest daughter Lü Lu to Liu Bang, and Lü Lu did not disobey his father's orders.
Liu
Liu Bang and Lü Yan
Lü Yan was very virtuous when he first married Liu Bang, and he was also busy with housework like other women, even for Liu Bang's son Liu Fei was treated as if he were not half harsh, and then Lü Yan gave birth to a son and a daughter for Liu Bang, that is, the later Han Hui Emperor and Princess Lu Yuan, after marriage Liu Bang often ran around, Lü Yan also took care of and supported the family with hard work, and the former rich lady married Liu Bang who had nothing, not only did not have a proud and arrogant young lady temper
On the contrary, she is diligent in running the family and filial piety to her in-laws, and she can really be regarded as a good wife who is rarely virtuous and virtuous, so why did Lü Yan, who was so virtuous and gentle in the early stage, become a "poisonous woman" criticized by everyone in the later stage? What is the deep hatred between her and Lady Qi? To deal with her with cruel human nature?
Mrs. Qi
After Lü Yan married Liu Bang, he did not live less and did not eat less, and later Liu Bang rose up to fight with Xiang Yu for the world, and Lü Yan stayed in his hometown, and as a result, Xiang Yu captured Liu Bang's father and Lü Yan, until Han Gaozu spent more than two years in the military camp of the Chu State in the fourth year (203 BC) before being released, and Lü Yan, who returned to Liu Bang's side, found that Liu Bang's side already had a favored Lady Qi, and Lady Qi was able to sing and dance and often drum and play the piano to accompany Liu Bang, and was favored by Liu Bang. Here Liu Bangqi Lady sweet and sweet Qingqing me, let the other side of Lü Hou's life is not good, Liu Bang every time he goes out to let Lady Qi accompany and throw Lü Lu in the harem, gradually the feelings between Liu Bang and Lü Hou will be estranged, and Lady Qi is also very pampered and proud, and she is young and beautiful and liu Bang is favored, she does not put Empress Lü Lu in her eyes at all, and begins to suppress Lü Hou openly and secretly, thus summoning Lü Hou to be jealous and beginning to harass Lady Qi everywhere, because Liu Bang took care of Her Lady Qi from harm. And these made Lü Hou look at the hatred in her eyes, and when Liu Bang died, her son Liu Ying became emperor, and she became the empress dowager and the first person to take revenge was Lady Qi, so she used very cruel means to make her a "human yan", and Lü Hou's atrocities against Lady Qi
In the Book of Han, it is recorded as follows: "The empress dowager cut off Lady Qi's hands and siblings, removed her eyes, burned her ears, drank medicine, and made her live in the toilet, and her fate was: 'Ren Yan'." The so-called "ren yan" is to cut off people's limbs, goug out their eyes, and have a poisonous throat and ears, so terrible punishment is terrible to think about, Lü Hou even took his son Liu Ying to visit, Liu Ying was cowardly by nature, and after seeing this situation, his spirit was greatly stimulated, and when he went back, he could not afford to ask about the DPRK and China, and he only indulged in wine every day and died after a few years. So why did Lü Hou hate Lady Qi so much? So much so that it was poisoned?
First of all, Lady Qi stole Liu Bang's favor, because Lady Qi's arrival shattered the beautiful dream of Lü Hou's husband and wife' inseparable love
Moreover, Lady Qi often said in front of Liu Bang that Lü Hou was right and wrong in a vain attempt to suppress Lü Hou, so that Lü Hou had a grudge against Lady Qi.
Secondly, Lady Qi wanted to take away the position of crown prince of her son Liu Ying, watching Liu Bang so much spoil Lady Qi, Lü Hou could only endure silently although she was resentful, and there was no hope for her own struggle for favors, so the only thing That Lü Hou could hope for was that her son Liu Ying could smoothly become the emperor of the Han Dynasty, but she did not expect that her own tolerance made Lady Qi openly challenge her position, and after Lady Qi gave birth to her son Liu Ruyi, Liu Bang favored herself, often saying good things about her son at Liu Bang's pillow, and also wanted Liu Bang to depose Liu Ying's position as prince , and made his son Liu Ruyi the crown prince,
Seeing that his only hope was also going to be robbed by Lady Qi, Lü Hou hated Lady Qi even more, and naturally could not tolerate this eye nail after he gained power.
Personally, I think that the reason why Lü Hou hated Lady Qi and even made Lady Qi a "human figure", although there was Lü Hou's heart being fierce in the middle, but the main reason was that Lady Qi herself made it.
