Lady Hook Yi was the favorite concubine of Emperor Wu of the Han Dynasty in her later years. There is also no clear evidence in the historical data that she was a scheming person - the legend that Emperor Wudi of the Han Dynasty broke the girl's unopened hand and put her into the harem must be a conspiracy, but it may not be the young girl's idea, perhaps only arranged by the family.

Emperor Wu of the Han Dynasty had six sons, which were not particularly "prolific" among ancient emperors. Moreover, Emperor Wu of Han lived for a relatively long time, and by the end of his life, three of his sons had died, and of the remaining three, one was ambitious and resentful, and the other was a good advocate and a joy to wander. The only person who could succeed to the throne was Liu Fuling, the youngest son born to Lady Hook Yi.
When Emperor Wu of Han died, Liu Fuling was only eight years old, and he was certainly even younger when he was established as a prince. Therefore, it was natural that Liu Che would worry that Fu Ling's mother, Lady Hook Yi, would control the government.
This is not Liu Che's over-concern, but too many lessons from the past. Soon after the founding of the Han Dynasty, Liu Ying succeeded to the throne at the age of sixteen and Lü Hou took control of the government. When Emperor Wu of Han arrived, he was sixteen years old and succeeded to the throne, first by his grandmother Empress Dowager Dou, who was in charge, so it was easy for the old lady to "follow the laws of nature, and then she was escorted to the cemetery by relatives and friends", and her mother, Empress Wang, came out to take care of things, which made Liu Che very depressed.
It's not just That Liu Che is depressed. After Lü Hou's death, the ministers chose liu heng to succeed him, one of the reasons was that bo ji, the biological mother of the acting king, had a low status and did not have powerful foreign relatives, which would not cause the harem to interfere in politics. The harem's interference in politics has become a thorn deep in the heart of the Emperor of the Han Dynasty.
Objectively speaking, whether it was Empress Lü or Empress Dowager Dou, they both maintained the rule of the Han Dynasty and were helpful to social stability and unity. However, while the country was stable, the Liu clan was undoubtedly squeezed out. In the struggle between imperial power and post-power, Liu Che, as emperor, certainly did not want houquan to prevail. When he was about to die, looking at his young son, who was only seven or eight years old, could he not worry about the recurrence of the old things?
Fearing that Lady Hook Yi would control Liu Fuling— which would almost certainly happen — Emperor Wu of Han would have to strike first. And what kind of hand is it? Of course, it was an excuse to kill Lady Hook.
Did Emperor Wu of Han have any real feelings for Lady Hook Yi? We don't know. But we know that even if there is affection, it cannot offset his love for Jiangshan Sheji.
He loves beauty, but he loves Jiangshan even more.
