What is the identity of Su Liu, a big shot in poverty?

Crossing into a tried and tested scholar, there is nothing around the house, and there is a blind old lady and his wife who just got married for half a year. Shoulders can't be lifted, hands can't be lifted, and technological inventions can't be done. Chyi Yu thought for a moment: It seems that there is only one way to go, that is, to study for the imperial examination.

Encouraging the world to be an official is just a gimmick, which is very rare in reality. If you want to embark on the road of imperial examination, you must have a stable source of income, otherwise it will be difficult to make ends meet. Therefore, it is imperative to find a business to do, in addition to paying off debts, but also to survive. There is an urgent need to solve the survival problem. Let's just say that a scholar is not useless in the legend.
