Lin Feng, the once-famous technology company CEO, owed tens of thousands of dollars in debt after his financing failed. He was forced to sell his house and car, and his wife left with their children. He lived in a ten-square-meter partition in an urban village; he worked three jobs a day to pay off his debts. He broke his leg while delivering food in the early hours of the morning and had to rely on instant noodles to survive. Just when he was desperate, he discovered that the old ladies in urban villages were actually hidden "renters." By helping the elderly develop a simple rental management system, he gradually regrouped and founded a rental service company that specializes in serving elderly landlords.
