Why did the Northern Wei Emperor kill his mother?

Emperor Wu of the Han Dynasty was the longest-serving emperor in the Han Dynasty. He was emperor for fifty-four years, but he was very suspicious in his later years. In the witchcraft incident created by the courtier Jiang Chong, the prince finally committed suicide. Although Emperor Wu of the Han Dynasty had six sons, after the death of the Prince, the issue of heirs was a headache.

In the end, he could only concentrate on his youngest son, who looked like himself in his later years, but he was only five or six years old at that time. He was worried that his mother's authoritarian power would shake Liu's world, so he had the idea of killing his mother. Hanwu's will ordered Liu Yuxin Fuling to kill his biological mother, Mrs Gou Jian, for Zhao Di. At that time, some people questioned it. Emperor Wu of the Han Dynasty said that the reason why ancient countries were in chaos was often because their masters were young and their mothers were strong. The hostess lives alone, arrogant and has no power to restrain herself. Haven't you heard about the Lv Hou incident? In this regard, some commentators have pointed out that "since ancient times, there have been many orders from emperors, and there is no such thing as Hanwu." "

After Mrs Gou Jian's death, some people couldn't understand the practice of killing Lizi's mother. "Zi Zhi Tong Jian" records an explanation of Emperor Wu: "He who knows right and wrong is stupid. Going to the ancient country is so messy, the mother is strong. A woman who lives alone is arrogant, and fornication is self-indulgence. You don't smell the evil in Lv Hou! So I have to go first.
