What are the achievements of ancient science and technology in China?

China's ancient scientific and technological achievements include papermaking, compass, gunpowder and printing.

1, papermaking

Papermaking is an important scientific and technological achievement in ancient China, which originated in the Western Han Dynasty.

Medical and pharmaceutical achievements

He used four diagnostic methods: seeing, hearing, asking and feeling to diagnose the disease 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.
