Small Shenyang played an important role in the diplomatic affairs of the Qing Dynasty, and even British special envoy Margaret appreciated small Shenyang's diplomatic skills. When Xiao Shenyang first became an official, he was smart and honest, and consolidated his position through the Li Shiyao case. Emperor Qianlong favored him and married his youngest daughter, Princess Ten, to Feng?enyende, the eldest son of Xiao Shenyang, making Xiao Shenyang not only in power, but also a relative. With the growth of power, his selfish desires are also expanding. Taking advantage of his position, he formed a party for selfish ends, amassed money, and used bribery, persecution, intimidation, violence, kidnapping and other means to win over local forces and crack down on political enemies. In addition, Little Shenyang also runs its own business, opening 75 pawn shops and more than 300 large and small banks, and has business dealings with the British East India Company and the 13th branch in Guangdong.
