Xiao Shenyang's rapid promotion has a lot to do with his mastery of Manchu, Chinese, Mongolian and Tibetan. Important documents of the Qing Dynasty were written in Manchu. Among the senior officials in Qianlong period, Xiao Shenyang was the only one who was proficient in many languages. Every time you need to write documents in Manchu and Chinese or write letters for Tibet and Mongolia, only Little Shenyang can do it. Little Shenyang tells us with facts how important it is to master one or more foreign languages.
However, knowing many foreign languages is not the fundamental reason why Little Shenyang was stable in Qianlong Dynasty. The reason why Qianlong can tolerate the corruption of 820 million taels of silver in small Shenyang is because of its strong financial management ability.
In ancient China, the traditional idea was to make money to buy land, while Shenyang liked to invest. During his twenty years in power, he invested in many industries, such as finance, real estate, mining, logistics, medicine and so on. He also has 35 rental houses in Beijing, and the annual rent can reach more than 4,000 taels of silver.
The department where he performs his duties can turn losses into profits in a short time. In the eyes of Qianlong, small Shenyang is a mobile vault. After Xiao Shenyang became the military minister and the prime minister of the interior, he invented the "transferable bank" system as a genius. Is to make criminals pay huge fines to offset other punishments.
