Back in the 1990s, she became rich through scientific research

Qin Hongfei woke up and went back to 1999 before the time travel. She was dealt a bad hand. Her father died at the beginning. Her mother was crazy and attracted countless hatred. She inherited the family shop and owed millions of debts. Her grandfather didn't love her and her grandmother didn't love her. Her sister dropped out of school early and got into the entertainment industry and was blackmailed. Everyone came to step on her.
It doesn't matter. With the experience of more than 20 years of scientific research in the time travel, she took over the family repair shop.
Repair electrical appliances?
Five hundred per time, and ten times the compensation if it breaks.
While repairing, she accidentally became famous. Everyone knew that there was a repair shop on Qinhuai Street. There were always people who paid to jump the queue. At first, it was the boss of an e-commerce company, and later it was a high-tech personnel in Yangcheng. - Why did even the professor of a senior college who was often asked to be interviewed by newspapers come in person? ?
Before meeting Qin Hongfei, Tang Jinnan's teacher said that women were stumbling blocks on the road to growth, and they would be chopped off one by one. After meeting Qin Hongfei, Tang Jinnan found that the teacher was misleading his students.
