Happy Little Housekeeper

Traveling back in time to the Dayu Dynasty and becoming a low-level housekeeper, Li Zhi discovered that his only golden finger was the common sense accumulated through using his mobile phone for thirty years in his previous life. He was not a top student and did not know how to make gunpowder glass, but he at least knew that the earth was round, bacteria could cause infection, supply and demand could be controlled, and... A few ancient poems that he had memorized in Chinese textbooks. That's it? This is enough to walk sideways in ancient times! Three generations of the Marquis of Changning died in the war, and the debt was 60,000 taels. There was only a house of female relatives and monsters all over the house. Li Zhi is submissive on the surface but arrogant on the inside. With his left hand, he uses modern management to rectify the houseworms, and with his right hand, he uses economic knowledge to deceive the black-hearted salt merchants. If it doesn't work, just recite a few lines of ancient poetry to calm the mood - don't ask, just ask because you are gifted. In the Yu Dynasty, which was surrounded by internal and external troubles and surrounded by wolves, Li Zhi relied on his extremely pragmatic principles and unambiguous venomous tongue to forcibly embark on a counterattack. The female family member of the Hou Mansion: "Steward Li, how many surprises do you have left?" Li Zhi: "Shh, I learned it by watching short videos."
