Aqiang is a delivery rider. He rides for 12 hours a day, saving 150,000 yuan to buy a house. In 2023, he saw a teacher’s “order-and-earn” contract in a group chat and thought he could make 30,000 yuan a week. He increased his investment, and after two weeks, the entire 150,000 yuan was gone. After his fiancée found out, they called off the engagement—and the house was gone too.
