The prototype of Deng Ying in "Dongchang Observation Notes" is actually the eunuch Ruan An. In history, Deng Ying was punished and died in Lingchi. Yang Lun, the cabinet scholar, personally mentioned the word "Zhijie" to him after his death. She and Deng, the author of "Dongchang Observation Notes", is a time-traveling eunuch novel that posits the Ming Dynasty. The male protagonist in the article is Deng Ying, a famous eunuch and traitor of the Ming Dynasty, and the female protagonist is a modern researcher on the history and culture of the Ming Dynasty.

Deng Ying’s comments

Deng Ying, the factory supervisor of Dongchang, is a gentle and gentle gentleman. In the first half of his life, he was well-educated and had great ambitions to cultivate himself and govern the country and bring peace to the world. In the second half of his life, his father was imprisoned for corruption, but he became a eunuch. He lost his dignity as a man overnight and the collective betrayal of his teachers and friends made him fall into the abyss.

His whole family was wiped out, he suffered corruption, his official career was hopeless, and his body was mutilated in Dongchang. He never lost his literary pride.

The outsider eventually becomes the insider. Yang Wan was unable to integrate into the feudal order with peace of mind, and could not look at the imbalances around her with a purely academic attitude and indifference. She was confused and struggling, and struggled to adapt. She respected him and loved him, and found the passion of this dynasty in Deng Ying. As a modern person, all she can do in this seemingly lifeless time and space is to try her best to open the door.

Let the young man in history, who once had a bright future and great success, be misunderstood, bear infamy, go to the execution ground, and die of execution, have a slightly better life. Deng Ying had no power, influence, or wealth, only a broken body. The appearance of Yang Wan became the last lantern in Deng Ying's life that had reached the end of darkness.
