For the history of science and technology in modern China, please refer to the history of science and technology in the People's Republic of China. For the modern Chinese science and technology, please refer to the science and technology of the People's Republic of China.

One of the earliest inventions was an abacus, a "shadow clock", and a starting project like Kong Ming Lantern. Four inventions, compass, gunpowder, paper, printing are one of the most important technological advances and became known only in Europe at the end of the Middle Ages in 1000 years. Tangyo (AD 618 - 906) was a time of great innovation in particular. Until the Qing Dynasty there was a lot of communication between the discovery of China and the West.
These four inventions are not necessarily summaries of the achievements of ancient Chinese science and technology. These four inventions are considered to be the most important scientific and technological achievements in China just because they are a powerful driving force for the development of European capitalism, which occupies a prominent position in the East-West exchange I will. Indeed, ancient China gained a score far beyond the four major inventions of agriculture, iron and copper metallurgy, coal and oil mining, machinery, medicine, astronomy, mathematics, porcelain, silk and wine making. Many inventions and discoveries contribute greatly to China's productivity and social life. Many are as important as at least four inventions and some are even more important than the four inventions.
