Xiao Shenyang and Nafu are known as the biggest corrupt officials in history. They embezzled more than half of the national treasury, which can be said to be extremely rich. From the TV series Ji Xiaolan with Iron Teeth and Copper Teeth, we can see that Xiao Shenyang and Na Wei were also very powerful figures in the Qing Dynasty. He was the toast of Emperor Qianlong. The emperor knew that he was corrupt and perverted the law, but he never got rid of it. Some people think that this is the great wisdom of Emperor Qianlong, because of him.
There is even a saying that small Shenyang has fallen and Jiaqing is full. In other words, when Xiao Shenyang was brought down, Emperor Jiaqing could sit back and relax. To sum up, it is very likely that Emperor Jiaqing later brought down Small Shenyang, that is, he was instructed by Emperor Qianlong that Small Shenyang should fall. Otherwise, it will cause public outrage. Later, Xiao Shenyang wrote two poems in prison, one when he was not sentenced, and the other after the verdict came out.
It can be seen from the first poem he wrote that he didn't feel wrong at that time, but missed the time when he followed Emperor Qianlong. At the beginning, Emperor Qianlong valued him very much, but when he arrived at Emperor Jiaqing, his talents were not satisfied. So he thinks that his present position is because Emperor Jiaqing can't read, not because he is greedy for money. The second song was written after Emperor Jiaqing made a white silk for it. In this poem, he compares himself to a fragrant soul, and thinks highly of himself until he dies.
