What were the great scientific and technological achievements in ancient China?

China is regarded as the country that invented the compass in the world. The invention of the compass is the result of long-term practice and understanding of the magnetism of objects by the working people in ancient China. Due to productive labor, people came into contact with magnetite and began to understand its magnetism. People first discovered the property that magnets attract iron, and later discovered the directivity of magnets.

Step 2 make paper

Papermaking is one of the four great inventions in China and an outstanding invention in the history of human civilization. China is the first country in the world to raise silkworms and weave silk. In ancient China, the working people spun silk from superior cocoons, and the remaining evil cocoons and diseased cocoons were made into silk floss by bleaching. After floating, some residual flocs will be left on the mat.

(1) Pre-Qin period: Bian Que was the most famous doctor in the Warring States period. Later generations regarded him as a "master of pulse science". He used four diagnoses: seeing, hearing, asking and cutting, and diagnosed the condition from the pulse condition. Pulse-taking is Bian Que's main achievement. Four diagnostic methods have become the traditional diagnostic methods of Chinese medicine, which have been used by Chinese medicine for more than two thousand years.
