Fulfillment: All the money earned was used to pay off debts. In October of that year, Zhang Renqiang received a call from his father, saying that after selling the pigs at home, his wife disappeared. This scared Zhang Renqiang half to death because most of the money from the past fish pond, pig farming, and scrap collection was in his wife's hands. After calculating, there were not many people in the whole family who had the ability to repay the debt for Zhang Renchun. Hardship: He was so tired that he fell asleep on the bus every day. In Zhouji Town, Huoqiu County, Zhang Renchun was once a well-known figure because he ran a factory and nursery, and could be considered a local leader in getting rich. This made Zhang Renqiang fall into trouble again with the early symptoms of hyperthyroidism. The next year, his cousin found Zhang Renqiang again and wanted to continue doing the building materials business. But due to lack of capital, Zhang Renqiang could only give up and let his cousin do it alone. Now his cousin can earn several million yuan a year, while Zhang Renqiang is still engaged in his old job - collecting scrap. Zhang Renqiang has a 14-inch TV, but the picture is unclear. Because there are guests, he turned on two energy-saving lamps, but the room was still very dim. He went out to collect junk before dawn and came back when it got dark. The couple quarreled at home, but outside they still paid the debt as usual. Zhang Renxiu felt wronged for her son and couldn't help but vent her anger on her husband. For the sake of repaying the debt, she didn't know how many times she had argued with her husband, but Tu Enpu remained unchanged: the money must be repaid, otherwise it would be shameful to be a person. Reporter: What are your plans next? But Ding Youquan never expected that last September, Zhang Renxiu actually took the initiative to send the money to his house. At that moment, Ding Youquan didn't know what to say. "I still remember the situation at that time, it was too moving, which made me feel really sorry for them." Ding Youquan said. When spring comes, Zhang Renqiang will continue to raise pigs and collect scrap iron. These jobs cannot stop. Before Zhang Renchun passed away, Zhang Renqiang once contracted a fish pond in his hometown, and life was still manageable, even having spare money to lend to his brother for business. But now this 1.2 million yuan debt forced him to leave home and find ways to repay the debt. He first thought of coming to the provincial capital Hefei to make some money. Dialogue with Zhang Renqiang: People die, but they should not leave behind curses. Zhang Renqiang: There is no question of worth or not, being a person depends entirely on conscience. (Reported by Wenbing and Gongli) Later, he started raising pigs again. Now in Feixi County, he has a pig farm of 600 square meters, capable of raising more than 400 pigs. This summer, his pig farm made a profit, earning 150,000 yuan. This money was also returned to the creditors, whoever needed it urgently would get it first. At the beginning, Zhang Renxiu had the idea of repaying the debt for her brother, but she was worried that her husband would oppose it. It turned out that Zhang Renxiu's concern was unnecessary. In her words, her husband Tu Enpu was a very "righteous" person. Not only did he not oppose it, but he was also very proactive, and even when Zhang Renxiu was angry about repaying the debt, Tu Enpu was more determined than her. Zhang Renqiang had no time to look for his wife, and he returned to Hefei to continue working because the huge debt was still unpaid. When the debtor sent the money, the creditor was moved almost speechless: "This makes me feel really sorry for them." Reporter: Did you resent your brother when you were tired? Brother Zhang Renchun passed away on January 2, 2009. In a few days, it will be the third anniversary of his death. These three years, Zhang Renqiang has never stopped. The hardships, only he knows clearly. Reporter: Have you ever felt tired these years? In Huoqiu's hometown, many people know that Zhang Renqiang and Zhang Renxiu have been paying off their brother's debt, and they all say they are good. "Everyone says it's great that you pay off your brother's debt, what do you think?" "He is my brother!" The usually reserved Zhang Renqiang rarely smiled, and the wrinkles on his face became deeper. Zhang Renqiang hopes that one day this land can be auctioned off, so that his brother's debt can be settled. Facing the final 100,000 yuan debt, Zhang Renqiang and Zhang Renxiu both feel powerless, they really have no money. At a dead end, Zhang Renqiang remembered the 5 mu 4 fen land bought by his brother when he was alive: if the government could auction it off, it would be enough to repay the 100,000 yuan debt. Currently, Zhang Renxiu and Tu Enpu live in two small rural bungalows. Over the years, for the sake of repaying the debt, they have spent all their savings. This year's business is slower than usual. Since all the money was used to repay the debt earlier, during the sluggish business period, she could only borrow money to maintain operations. 1.2 million yuan in huge debt, how could Zhang Renqiang possibly repay it without eating or drinking? But now, this huge debt is down to the last 100,000 yuan. This is thanks to his younger sister Zhang Renxiu. In a scrap metal recycling station near Daputou in Hefei, Zhang Renqiang is cutting the scrap metal collected during the day. But where should this huge amount of money come from to repay the debt? Zhang Renchun had a son and a daughter. His son works in Beijing, earning just enough to get by; his daughter works as a kindergarten teacher in their hometown, with a monthly salary of over 1,000 yuan, unable to contribute money to repay the debt. In 1995, due to poor performance, the steel rolling mill was "taken over" by the Zhouji Town government and later sold to two locals. However, the government also sold the agricultural machinery repair plant in the same courtyard. Although Zhang Renchun later sued and won compensation locally, the issue of the 5 mu 4 fen land remains unresolved to this day. Zhang Renqiang asked around and learned from his fellow villagers that his wife left because she could not bear seeing him repay his brother's debt. This news dealt a heavy blow to Zhang Renqiang. He lost his right-hand partner in life and career, a family member he had lived with for decades, and the money he worked hard to save, which was supposed to repay others' "debts". Zhang Renchun rented 85 mu of land to grow a nursery, planting camphor and magnolia trees. He was busy in this nursery all day, but due to overwork, he developed problems with his lumbar vertebrae. In May 2008, after investing a large amount of funds in the nursery, Zhang Renchun became seriously ill and bedridden for 7 months until his death. By this time, he had borrowed 1.55 million yuan for his business, including 200,000 yuan from his younger brother Zhang Renqiang, 150,000 yuan from his elder sister Zhang Renxiu, 400,000 yuan from the Zhouji Town Credit Union, and the remaining 800,000 yuan borrowed from friends. During Zhang Renchun's serious illness, the nursery was neglected and overgrown with weeds. Not long after his death, a mysterious fire burned all 85 mu of camphor and other trees to ashes. Zhang Renchun's years of effort in Hubei, treating hyperthyroidism at the best hospital, yielded no returns, leaving behind only a charred piece of land and over 1 million yuan in huge debt. To come up with ideas to make money, Zhang Renqiang changed from collecting all kinds of waste to specializing in scrap iron recycling. Zhang Renqiang often appears near Daputou in Hefei, where there is a scrap iron recycling station opened by his friend. Every time Zhang Renqiang collects scrap iron, he brings it here first for cutting, making it smaller before selling it. Speaking of this piece of land, there is a story. As early as 1989, Zhang Renchun set up an agricultural machinery repair plant locally, then agreed with the villagers to buy 5 mu 4 fen of land at a price of 13,700 yuan per mu to build the factory. In 1991, he set up another steel rolling mill, placing both factories together within the same courtyard. In the Youth Community building on Ningguo Road, Zhang Renqiang rented a small room of more than ten square meters on the third floor, with a monthly rent of 350 yuan. There were two beds in the room, no place to hang clothes, and the beds were piled high. There were no chairs to sit on, so both host and guest sat on the bed. Now it's already "counting nine," Zhang Renqiang's home is damp and cold, the window glass is cracked in several places, and cold wind blows directly into the room. While talking to the reporter, Zhang Renqiang always curled up. Talking about repaying his brother's debt, he said solemnly, "If we don't repay it, who will?" Zhang Renchun's father served as a village cadre for 30 years, and his mother once won the labor model award in the county. This family was quite prestigious locally. But after Zhang Renchun's death, a huge debt of millions remained. What to do? The family carefully discussed and finally reached a clear conclusion: even though a person dies, the debt does not rot, and the money must be repaid. Zhang Renqiang and Zhang Renxiu stepped forward and decided to repay the 1.2 million yuan for their brother. Zhang Renchun had four siblings, he was the eldest. The second brother Zhang Renqiang and the third sister (elder sister) Zhang Renxiu had relatively good living conditions, and thus became the "creditors" of the older brother. The fourth sister Zhang Renlan maintained her livelihood through pig farming, living a hard life. Zhang Renqiang came to Hefei at the age of 54. To repay his brother's debt, he endured more hardship than young people, excelling in collecting junk. He transformed from a wandering "junk king" into a small boss of a recycling station. With the help of his cousin, he also ventured into some building material businesses. In 2009, it was Zhang Renqiang's first year of repaying his brother's debt, and also a year of small achievements in Hefei. Whether it was waste recycling or building material business, he did very well. However, an unexpected event occurred. Without any special skills, what could Zhang Renqiang do? When he arrived in Hefei, he realized how difficult it was to make money in the city. Gradually, Zhang Renqiang began collecting junk, because this job required no cost or skills, only his own efforts. Reporter: Do you regret all the sacrifices you've made? Zhang Renqiang: It's definitely tiring, but how else can you make money without being tired? Reporter: Is it worth it? Zhang Renqiang: My brother and I are both our parents' sons, isn't the money he owes the same as mine? People die, but they should not leave behind curses. Reporter: What's your next plan? Zhang Renqiang: Repay the debt. Over the past three years, Zhang Renqiang has repaid more than 300,000 yuan of his brother's debt, leaving only essentials for himself. In the rented room of Zhang Renqiang, he only bought one thing for himself - an old air conditioner costing 800 yuan. This is the most luxurious "luxury item" for someone who earns 100,000 yuan a year. Zhang Renqiang worked hard. By the end of the year, he gave all the twenty-some ten thousand yuan he earned to the creditor, without keeping even a bit of capital. There are nearly 20 creditors, some urge urgently, some less so. Among them, Ding Youquan never urged. Ding Youquan once worked with Zhang Renchun, and when Zhang Renchun couldn't pay the workers' wages, Ding Youquan always lent him money to cover it. After Zhang Renchun's death, he owed Ding Youquan nearly 80,000 yuan. He said it was embarrassing to ask for it because he knew Zhang Renchun was already in difficulty before his death, and his family was even more strained after such a long illness. In the 1990s, Zhang Renxiu ran a pig farm with her husband thyroiditis. Compared to Zhang Renqiang, Zhang Renxiu's situation was slightly better. But after taking on the debt, all the accumulated wealth was consumed. Zhang Renxiu repaid the huge debt for her brother, but her own business incurred a debt of 200,000 yuan. What made her even more embarrassed was that her 27-year-old son working in Hefei had no house, and his marriage had to be postponed. This made her feel very uncomfortable.
