Xiao Shenyang's classic line is: "I am afraid of people's unpredictability when I obey orders." No matter how big or small eunuchs are, they are not afraid of their master, so I spread my minions widely for a visit. " In addition, this line does not conform to historical facts. Xiao Shenyang was a minister during the Qianlong period of the Qing Dynasty. He was proficient in Manchu, Chinese, Mongolian and Tibetan. After forty years of Qianlong (1775), he was promoted to the bodyguard of Gan Qing Gate. Later, he entered the palace cabinet and held many important positions. He has held many important positions, including chief university student, minister of military aircraft, minister of official department, minister of the Ministry of Housing, minister of punishments, minister of Li Fan Academy, and also served as head of the Ministry of Internal Affairs, bachelor of imperial academy, editor-in-chief of Sikuquanshu, minister of guards, head of infantry, etc. His power and position were very prominent, and he was one of the important figures in the court at that time.
In addition, the line "touch the piano with a gossamer, unfinished is the saddest string" is more like a poem written by a poet or scholar, but I'm not sure who said it in history. If you are interested in the specific source of this line, you can continue to conduct in-depth research or inquiry.
