In the history of human civilization, there have been many great inventions and creations that have made tremendous contributions to the development of the world. Among them, the "Four Great Inventions" of ancient China are undoubtedly one of the most representative achievements. This article will introduce the content of the four inventions and who first proposed them.

Firstly, the content of the Four Great Inventions:

1. Papermaking: Papermaking is one of the most important inventions in ancient China. The earliest papermaking technique can be traced back to Cai Lun in the Western Han Dynasty. He improved the papermaking process, making paper more suitable for writing and printing, which greatly promoted the dissemination and development of culture.

2. Printing: Printing is another important invention in ancient China. The earliest printing technique was wooden block printing, which later developed into movable type printing. The emergence of printing made the production of books more convenient, greatly reduced the cost of books, and provided strong support for the popularization and dissemination of knowledge.

3. Gunpowder: Gunpowder is an important invention in ancient China, which was initially mainly used in Taoist alchemy and other fields. With the development of gunpowder, it was gradually applied to the military field, such as rockets and cannons, greatly changing the form of war.

4. Compass: The compass is a great invention in ancient China. The earliest compass was the "Si Nan" based on lodestone. The emergence of the compass provided an important tool for navigation, enabling ships to accurately find their direction in the ocean, creating conditions for world trade and cultural exchange.

Secondly, who first proposed the Four Great Inventions:

The Four Great Inventions were first proposed by the British scholar Joseph Needham. When studying the history of ancient Chinese science and technology, he found that these four inventions had a far-reaching impact on the development of world civilization. Therefore, he called papermaking, printing, gunpowder, and the compass the "Four Great Inventions".

In conclusion:

The Four Great Inventions are the crystallization of ancient Chinese wisdom, which have made tremendous contributions to the development of world civilization in their respective fields. Joseph Needham, a British scholar, was the first to propose the concept of the Four Great Inventions, emphasizing the important position of these four inventions in world history. We should be proud of these great inventions and continue to carry forward the spirit of innovation, contributing to the progress of human civilization.
