Go Do Business in Ancient Times

My name is Lin Hao, I am very poor and have no money. Alas, but I have a door that can transport me to ancient times. So what, you say, what do you think will happen. Once someone bullies me, wants to kill me, and pulls out a modern weapon, guess what they will do. You ask me if I am not poor, how can I have money to buy weapons? Alas, wouldn't I make money by selling the washing powder, condiments, sugar, and salt to the natives over there? You said I only make low-end products, no no no. Then I sold the A4 paper and pen to dignitaries and businessmen. Oh, by the way, I sold the gold-inlaid pen to His Majesty the Emperor. Guess what will happen. What, you said I only make money from men, which is unfair to women. What if I sell a complete set of Hua Xizi's cosmetics to the queens, nobles, maids, and the wives of princes and ministers in the palace? What, you said they are all sold to rich people, but what about ordinary people? It's easy to handle. Ordinary people need pens, so I will sell them ballpoint pens and pencils.
