What are the little-known great achievements in the history of China?

Has made achievements in the field of basic scientific research. Great achievements have been made in human gene sequencing, carbon nanotubes and nano-new materials, CAMBRIAN life explosion research, MEMS research, South China Sea ocean drilling and so on. Emerging interdisciplinary subjects such as surface science, nonlinear science, cognitive science and earth system science have developed rapidly. The construction of eight major national scientific projects, such as the Chinese mainland scientific drilling project and the large-area multi-target optical fiber spectrum astronomical telescope, has created good conditions for basic scientific research in China.

Breakthroughs were made in high-tech research and industrialization. Major breakthroughs have been made in space high technologies such as manned space technology, launch vehicle and satellite technology. Breakthroughs have been made in two-line hybrid rice, genetic engineering drugs, sequencing of transgenic animals and plants and related genes, diagnosis and treatment of major diseases, and the overall level of biotechnology in China is close to that of developed countries. Great achievements such as HDTV, Shenwei computer, large-size monocrystalline silicon material and skin stem cell regeneration technology have made China leap into the world's advanced ranks in corresponding fields. The development of national defense science and technology has laid a solid foundation for strengthening national defense strength and promoted the technological progress of national defense industry.

Industrial and agricultural science and technology have made progress. In agricultural science and technology, more than 600 new varieties were cultivated during the Ninth Five-Year Plan period alone, and the output per unit area increased by about 10%. The popularization of some important technologies, such as water-saving technology for dry farming of rice, ABT plant regulator, and plastic film mulching cultivation of dry wheat during the whole growth period, has effectively guaranteed the realization of the goal of increasing grain production in China.

Some major technological breakthroughs have been made in industrial science and technology, which have improved the technical level of key industries. A series of important achievements have been made in the industrialization of digital program-controlled switches, oxygen-coal enhanced ironmaking technology, nickel-hydrogen batteries and amorphous materials. Combined with a series of major national construction projects, such as Three Gorges Project, national economic informatization, integrated circuit and Taishan Nuclear Power Station Phase II, a number of key technologies have been overcome through introduction, digestion, absorption and innovation. Mastered the design and manufacturing technology of several major complete sets of technical equipment. The popularization and application of a number of important technologies such as computer aided design (CAD) and computer integrated manufacturing system (CIMS) have greatly improved the technological innovation ability of enterprises. The implementation of a number of major projects, such as innovative drugs, utilization and protection of water resources, well-off housing, dating project of Xia, Shang and Zhou Dynasties, the second phase project of China Science and Technology Museum and the construction of a number of popular science facilities, have promoted the development of social undertakings.
