Lu Bei, a poor scholar in Ningyang County.
How poor are you? Six buckets of rice per month is enough to eat for half a month, and the remaining half is dependent on dreaming.
He has a "special power" - everything he looks at is like settling accounts.
When setting up a teaching assistant, he calculates the cost and profit; when running an academy, he calculates the input and output; when he is a magistrate of a county, he calculates the tax revenue;
Even when chasing girls, he made a "Cost-Benefit Analysis Table of Pursuing Mu Wan".
Others study in order to become an official, but he became an official in order to... Legitimately do more business.
Others rely on backstage, smooth beards, and qualifications to become an official.
He only relies on three things to become an official: ledgers, data, and a mouth that is not afraid of offending people.
From the seventh-rank magistrate to the third-rank minister, he won the court with a single account and was called the "God of Wealth and Wealth" by the people.
The emperor asked him to take charge of the country's finances. He said, "Okay, but I have to change the imperial examinations by the way. Officials who can't settle accounts should go home and farm as soon as possible."
