Last time, liu Zhao's ascension to the throne, for Empress Dou and Cai Lun, hidden dangers have long been buried!
After all, Liu Zhao was not Empress Dou's biological son, and as Liu Zhao grew older, his mind would gradually improve.
Empress Dowager Dou was also worried that if one day he knew the truth, he would not retaliate against himself!
However, the one who is most worried about this matter is actually Cai Lun!
If his patron Empress Dou falls, his future will be over!
At this time, Cai Lun still took the same approach as he did then, close to the empress!
Liu Zhao's empress Dowager Yin had a similar personality to Empress Dowager Dou, who was very sinister and liked to play conspiracies and tricks to harm people.
However, Liu Zhao was a decent person, with Liu Zhaozhen guarding, the Yin clan did not dare to mess around.
Cai Lun observed for a long time, he felt that Liu Zhao's empress might not be reliable, so he did not take the initiative to please, until after Empress Dou's death, Cai Lun found another woman to rely on.
This woman's name is Deng Sui!
Deng Sui was not only an ordinary nobleman, she was also the granddaughter of The Founding Father Deng Yu after the famous door.
She is not only beautiful, but also reads and learns from an early age, knows how to understand her subordinates, and most importantly, she has a good personality, is humble and courteous, and does not fight with others.
Emperor Liu Zhao liked this man.
Within a few years, everything did not go as Cai Lun expected, and the yin empress at that time was deposed by Liu Zhao because of some witch curses, and the new empress was Deng Sui.
However, before Deng Sui was made empress, Cai Lun was already very close to her.
The reason why people can succeed is that they still need vision!
After Cai Lun climbed to the position of new empress, he made another unexpected decision.
What is the decision?
Actively request a downgrade!
He asked Empress Deng to demote herself from the position of Zhongchang Attendant to Shangfang Ling.
As a direct consequence of this, his monthly salary was immediately reduced by 2/3.
Why did Cai Lun do this?
Because he is not looking at immediate interests, but on the long-term future.
Shang Fang ordered the contents in charge, including pen, ink, paper and other internal organs.
Empress Deng's hobby was to sing poetry and wander between calligraphy and painting.
It was in this process that in order to get closer to Empress Deng, Cai Lun exerted his ability to study hard.
He seriously studied the technique of calligraphy and painting, and finally came up with a sensational invention - Cai Hou paper!
This kind of Caihou paper is different from the previous court paper, in the past, people wrote and painted, etc., all on bamboo or cloth.
The Later Han Dynasty Book of Cai Lun records:
"Since ancient times, the book has been woven with bamboo jane, and its use of silk is called paper. Expensive and simple, it is not convenient for people. ”
That is to say, people at that time called a kind of satin cloth specially used for writing "paper".
Satin is expensive, used to make clothes, can also be worn repeatedly, reused, but used for writing, it is too wasteful.
And what about bamboo tablets? Nature is free to use, almost no cost, but too heavy, too troublesome, inconvenient to use.
As for the other kinds of materials that are not commonly used, then we will not mention it.
The "paper" technique improved by Cai Lun makes the raw materials simple and easy to obtain, and the paper made in the end is cheap and of high quality, which is very suitable for writing.
So what raw materials did he use?
"Rennai deliberately uses tree skin, hemp head, cloth, and fishing nets as paper."
Bark, hemp heads, rags, broken fishing nets, that's the raw material!
These things, that is, some garbage waste in ordinary life, are just natural economic conditions in ancient times, and these garbage will not pollute the environment.
Therefore, the invention of Caihou paper is not only a node in the history of human civilization, but also a very successful case of waste recycling.
Moreover, I can responsibly say that in human history, Cai Lun is definitely the most successful person in waste recycling.
As for why this kind of paper is called "Caihou paper"?
Let's break it down next time!
