The Country Paid 30,000 Yuan for Me, and I Paid Back 5 Trillion Yuan

In 1955, I was a poor little boy who came back from the United States. The motherland paid a debt of US$30,000 for me. I bit my finger and wrote a letter in blood: My life belongs to the country. The system awakened, and I started the research and development of "Death-Free". Learn on your own, ask workers, challenge experts, and teach disciples. Plastics, chips, photolithography machines, aerospace engines... Even the drinking fountains in Africa were designed by me.
