At the age of 35, his savings of 350,000 yuan were wiped out, he was burdened with debts of 150,000 yuan, his house was mortgaged, and he had not eaten a grain of rice in four days. When the balance on my bank card was only 2,550 yuan and everyone thought I would jump off the building, I stared at the futures market and smiled. I don't have any inside information, I don't rely on cheats, and I don't write cool articles. I rely on sorting out financial data published on the Internet and using my first-hand orders on soybean meal futures to carve out a bloody path. This is a living record of debtors and a real textbook on realizing information gaps.
