He didn't change his life on the day of execution, but finished his experiment and designed the first generation brushless electric excitation motor in China on the last day with a limited time. The influence of this experiment is not small, and Li Hongtao's inventions, large and small, were made during his imprisonment, so the detention center applied to the superior for a suspended execution of Li Hongtao's death sentence.

Li Hongtao, known as the most legendary death row inmate in China, was still doing experiments one week before his execution. Surprisingly, the detention center specially invited experts to help him with the experiment.

Finally, on the last day before the death penalty, Li Hongtao finished his experiment. However, through the detention center in Li Hongtao, which directly or indirectly benefited a lot, he applied to the superior for a reprieve, and the superior agreed.

Li Hongtao, known as criminal genius by human beings, once stole the official seal of a bank and a police car. With his super memory, he copied the car keys of a brand owner and stole the car. He also escaped from prison twice. Every time Li Hongtao enters the prison again, he has doubts. However, it is such a person who invented many patents, large and small, during his imprisonment.

Li Hongtao's great invention not only reduced his sentence bit by bit, but also indirectly helped the detention center to improve its management system, making Kunyi Detention Center one of the "20 model detention centers in China".

At this time, it suddenly occurred to me that knowledge can change fate. When this sentence is used in Li Hongtao, it is really a perfect interpretation and embodiment.

In 2009, after Li Hongtao was released from prison, he really started his life as an inventor.
