What are the four major inventions and the three plains in our country?

Four major inventions: the compass, papermaking, printing, and gunpowder.

Three major plains: the Northeast Plain, the North China Plain, and the middle and lower reaches of the Yangtze River Plain.

The Four Ancient Civilizations are the collective names of the four ancient civilizations in the world that are highly recognized internationally. They are ancient Babylon (located in Western Asia), ancient Egypt (located in North Africa), ancient India (located in present-day India, Pakistan and other countries, located in South Asia), and China (located in East Asia).

The Four Great Inventions are a point of view on the history of Chinese science and technology, which refers to the four inventions that had a great impact on the world in ancient China, and are important creations of the ancient Han working people, referring to papermaking, compass, gunpowder and printing.

China's main plains: Northeast Plain (composed of Liaohe Plain, Songnen Plain, Sanjiang Plain), North China Plain (also known as Huanghuaihai Plain, Huaihe Plain in the south), Yangtze River Plain (Taihu Plain, Jianghuai Plain, Poyang Lake Plain, Dongting Lake Plain, Jianghan Plain), Pearl River Delta Plain, Weihe Plain (also known as Guanzhong Plain), Chengdu Plain, Hetao Plain, etc. - Common Sense Geography.

The scientific and technological achievements created by the four ancient civilizations have made significant contributions to the history of the development of human civilization. They share many similarities and differences. They all originated in the great river basins, and the natural and geographical conditions of these places are relatively superior, especially the rivers provide fertile alluvial plains and favorable irrigation conditions, which greatly promote the development of agriculture, so as to develop other science and technology on this basis, and create great ancient civilizations.

At the same time, their science and technology are all produced from social practices and belong to the same type, that is, the Bronze Age model of agricultural practice. As a result, their science and technology have something in common in many aspects, and they have achieved brilliant achievements in many aspects. However, due to differences in production practices, there are still many differences in their science and technology.

Egypt paid more attention to geometry due to the need to re-measure the land after the flooding of the Nile, and at the same time, in order to preserve the corpses, its medicine was also more developed, and the pyramids also reflected the great achievements of its engineering; Babylon, on the other hand, relied on the astronomical calendar for agricultural production, so its astronomical calendar was relatively developed, and its arithmetic achievements were also very prominent; India, on the other hand, is more influenced by religion, its medicine is more developed, and people attach importance to pure speculation, and Buddhism is the religion with the highest level of philosophy in the world. On the basis of practice, our Chinese ancestors created a developed handicraft industry and accumulated rich theoretical achievements, but they were not or rarely dominated and infiltrated by religious thought. From the following table, we can see the comparison of the scientific and technological achievements of the four ancient civilizations:

See Table) The four ancient civilizations have all made brilliant scientific and technological achievements, and their scientific and technological achievements have spread all over the world, and have made indelible contributions to mankind for a long time.
