My own uncle's family started by opening a tea shop next to high school. They have been doing it for more than ten years, and their income is considerable. My cousin also studied for a week and then opened her own shop. It is easy to get started and the cost is extremely low. I'll tell you a story about my wife's cousin subverting your three views. She was originally a civil servant, and her daughter-in-law was also a supernumerary in the community. Then they spent more than half a million dollars, picked up a book and put it in front of a university in Hechuan, Chongqing. However, they returned to their capital within a year, and their profits were predictable. The next year, they opened another one in the main city of Chongqing. Today, I heard that another one opened in front of another university in Hechuan. At present, they are decorating and recruiting people. There are three companies. And the shops next to the school are tax-free! In this society, only those students earn the best money, because stupid people have more money. . .
