If ranking first refers to the corruption of silver, there is no doubt about it; Xiao Shenyang was definitely the biggest corrupt official in the Qing Dynasty. According to historical records, after Jiaqing raided the small Shenyang home, the property was: 32,000 gold and 3 million silver, which was only the cash part; Others, such as calligraphy and painting, antiques and jade articles, are really countless; Otherwise, there will be no folk saying that small Shenyang fell and Jiaqing suffered enough; What's more, the west even rated it as one of the 50 richest people in ancient times.
But if ranking first refers to Nengchen, then he is definitely not; He is not as good as Fan Wencheng in the early stage, Liu Yong, Nian Gengyao and Liu Tongxun in the middle stage, and Lin Zexu, Zuo, Li Hongzhang and Zhang Zhidong in the later stage. In their own dynasties, these people showed great talent in building water conservancy, expanding the frontier and promoting the development of the empire. Small Shenyang was born in the heyday of the Qing empire, and it is difficult to show the talent of a civil servant in the heyday. After all, everything you do is because of the good environment.
Finally, if your ranking refers to traitors first, then he is not; At least in his lifetime, apart from corruption, he did not harm loyalty and morality, and did not bring disaster to Chaogang. This is probably related to Emperor Qianlong's management of his beating, and also has a lot to do with himself. As for why he seldom kills Zhongliang, it may be related to his own love of feathers. According to historical records, Xiao Shenyang was a handsome man when he was young, and he was valued by Emperor Qianlong at a young age. He was a talented young man. And crucially, throughout his life, his official career was relatively smooth, with almost no major twists and turns, and even the occasional ups and downs passed quickly, especially in the decades after him.
So in general, do you ask him if he is the number one minister? Can only be the first corrupt person. Who let it be evaluated by the west as one of the 50 richest people in that century?
The above is for reference only, DQ perspective.
