What are the four great inventions of China in modern times?

1. Super hybrid rice: In 1970s, China became the first country in the world to successfully cultivate hybrid rice and put it into production on a large scale. For this reason, Yuan Longping has successively won many domestic awards such as the National Special Invention Award, the First National Highest Science and Technology Award, and 1 1 international awards such as the United Nations Science Award, the Wolf Award and the World Food Award, and was elected as an academician of the American Academy of Sciences in 2006. At present, the high yield per mu of super hybrid rice is 847 kg, which indicates that the breeding research of super hybrid rice in China has surpassed itself again and continues to lead the world. This achievement is of epoch-making significance for solving the most basic food problem of mankind, and should be listed as the greatest contribution of modern China to mankind.

2. Laser typesetting of Chinese characters: This achievement has opened a smooth road for Chinese characters to bid farewell to movable type printing, which is the most voluminous text in the world. It is of great significance to realize the modernization of press, publication and printing in China. It has aroused the amazement of the printing industry in the contemporary world, and is known as the second revolution of printing technology in China. Chinese can be written into computers, which means that other non-phonetic languages in the world can also be written into computers. China's wisdom has made outstanding contributions to the world!

3. Synthesis of Insulin: 1965, scientists in China completed the synthesis of bovine crystalline insulin, which was the first time in the world to synthesize peptide-like bioactive substances artificially. The first bioactive protein was synthesized artificially, which broke through the boundary between the field of general organic compounds and the field of bio-polymers with information concentration, and took an important step in the long process of human understanding of life phenomena.

4. Compound artemether: Compound artemether is the first drug with a brand-new chemical structure discovered in China, and it is also an original drug widely recognized internationally in China. By the end of 2005, it has been designated as the first-line drug for malaria treatment by 26 Asian and African countries, which is a milestone in the history of malaria treatment. Compound artemether is still the only patented drug widely recognized and sold in the world in China, and it is also the only drug truly going global in China.

China didn't invent the laser technology, atomic energy, semiconductor and electronic computer upstairs.
