Take He Shen House, the richest bureaucrat in Qing Dynasty, as an example. Liu Quan, the housekeeper of He Shen, is in charge of He Shen's foreign business, reception and gifts, while Xiao Shenyang is in charge of He Shen's shops and even the tax revenue of Chongwenmen.
With the help of Liu Quan alone, he managed the Shiha sea area of Nuoda in an orderly way, with almost no mistakes. It can be said that it is because of a housekeeper like Liu Quan that he has made "outstanding achievements" in a foreign land.
