Cai Lun came from a family of blacksmiths and was recommended to enter the palace by officials who mined cast iron. He was educated in the enlightenment of rural studies, so he had some knowledge of Confucian classics. In addition, he was very familiar with the techniques of iron smelting, casting, hemp cultivation, and silkworm breeding, which laid the foundation for his later success in the imperial palace."
When it comes to Cai Lun, everyone must be very familiar with his improved papermaking techniques. But what everyone doesn't know is that Cai Lun was actually a eunuch, and finally died of "eunuch interference in politics", and his political behavior was not impressive.
In 75 AD, he entered the palace as a eunuch, because he was clever, good at observing colors, and was particularly good at taking sides, and soon he became his vassal empress Dou.
But at that time, Dou shi was childless, so he regarded Song Guifei, who had a son, as a thorn in his eye and a thorn in his hand. In order to consolidate the power of the Dou clan, she tried everything to get rid of her.
Just in time, Princess Song Guifei fell ill and was seduced into saying that wild rabbits could cure diseases, so she ordered people to look for hares. This gave Dou a once-in-a-lifetime opportunity. She joined forces with her ministers to sue Princess Song guifei for witchcraft. Song Guifei was sent to prison for review, and it was Cai Lun who was in charge of hearing the case at that time. Cai Lun had already attached herself to Empress Dowager Dou, so how could he let her go? As a result, Princess Song Guifei died unjustly in prison. Because of his meritorious service with Empress Dowager Dou, Cai Lun rose straight up for a time and served as a constant attendant.
After Dou Hou's death, he soon attached himself to the new empress Dowager Deng.
The history teacher will never tell you that Cai Lun's improvement of papermaking is not how ambitious he is, but to please a woman--- Deng Sui.
Tang shi is full of poetry books and likes to dance and ink. In order to curry favor with Tang Shi, Cai Lun improved the art of papermaking. Therefore, it was favored by Empress Deng.
So why did he later commit suicide by taking poison?
In 121 AD, Emperor An of Han, the grandson of the Song nobles, ascended the throne. The case of Liu Qing's succession to the throne was immediately tried, and Cai Lun was also implicated in the persecution of The Song nobles. Cai Lun knew the consequences of being interrogated by Lieutenant Ting. Commit suicide by taking poison after bathing and changing clothes at home!
