When the male protagonist woke up, he found that he was "Shen Sanlang", a small grocery store owner who had just died of illness and was heavily in debt in Xi City, Chang'an. Facing a wealthy family, a vicious creditor (who may be the younger brother of a local gangster), and a completely unfamiliar environment, I was extremely panicked.
In order to pay off debts and survive, he was forced to take over a small shabby shop. All kinds of life jokes were made: not knowing how to make a fire on the stove, not recognizing the face value of copper coins, almost shouting "Your Excellency" when meeting an official to reveal his secret, being shocked by the Tang Dynasty "takeaways" (food sellers walking around the streets), etc.
