When people think of slave society, they immediately think of slave owners brutally servitude slaves and cruel use of slaves for fun, and use slaves for burial after death, so they always think that slave societies are uncivilized. In fact, it was this first class society that began the era of human civilization.

The so-called civilization refers to the degree and state of development and progress of human society. It is related to the ability of human beings to transform the world, and it can also be said to be the result of human understanding and transformation of the world.

Civilization and incivility are relative. The degree of civilization is not immutable, and it is always accompanied by the development of the productive forces and constantly moving from the lower to the higher. The higher the degree of civilization in a society, the less human beings are controlled and dominated by natural forces, and the stronger their ability to understand and transform the world.

If you compare a slave society with a socialist society, it is, of course, too barbaric. However, if we look at it historically, we will realize that the replacement of primitive society by slave society is a historic leap in the era of human civilization to replace the age of barbarism.

First of all, judging from the results of human transformation of the world, in primitive societies, people could only flee to high places or climb trees to escape in the face of floods. But in a slave society, people were able to overcome floods by damming and channeling them, which shows that there has been a great improvement in man's ability to overcome nature. Judging from the tools, ** and wine utensils unearthed from the cultural sites of the Xia Dynasty in Henan, it reflects the technology of smelting bronze and the level of craftsmanship of manufacturing utensils at that time.

The unprecedentedly large bronze "Simu Wu" tripod unearthed from the military attache village in Anyang, Henan Province, is a symbol of the development level of the social productive forces of slaves. From the shape and ornamentation, it can be seen that its grandeur and exquisite craftsmanship are rare in the world. Due to the improvement of smelting technology, metal tools are widely used.

These are the great achievements of human transformation of nature, which is enough to prove that the society at that time has entered a period of real industry and art.

Secondly, from the perspective of the degree of human civilization. In primitive societies, the products of labor often could not meet people's minimum living needs, so that the phenomenon of cannibalism occurred. Within the clan, men and women live together, and a group marriage system is practiced.

People are in a state of ignorance, "but they know that there is a mother, but they do not know that there is a father". In a slave society, prisoners were no longer killed, and a large number of prisoners were used as slaves for production and labor, and simple cooperation was practiced. This improved labor efficiency and promoted the development of production under the condition of backward production tools at that time.

Group marriages have also been replaced by marital marriages between men and women. In particular, the invention and application of writing laid the foundation for human civilization and enabled the rapid development of human spiritual production, which in turn promoted the development of material production, and the whole society took on a new look that was different from the past.

Therefore, the replacement of primitive society by slave society greatly promoted the development of productive forces, and also promoted the development of spiritual production on the basis of material civilization. Of course, this development is based on brutal economic exploitation and political oppression. It was this system of exploitation and oppression that adapted to the requirements of the development of the productive forces at that time, and enabled mankind to begin to enter the age of civilization.

I won't answer though. But there is something wrong with the title itself. First of all, the existence of the Xia Dynasty is not certain. China is also not a slave society, unlike the Western definition, our "slaves" are only servants.

A community is a community of social life.

Historical direction representation: the most commonly used is the (chronology) representation, and the most accurate is the (chronological scale) mathematical representation: scale = example: 1) 1:1000

3) One in a thousand.

The legend includes various (symbols) and their (textual descriptions).

There are three ways to represent the scale: three methods for judging the direction on the line, number, and text maps.

Usually the top of the floor plan is set as north and the bottom is south; The left is west, and the right is east.

Some maps have right-pointing signs, and people set directions on the maps according to the directions.

A map with a graticule can be used to determine the direction based on the latitude and longitude lines. The meridian lines indicate the north-south direction, and the latitude lines indicate the east-west direction.

Community Type The category that characterizes the type of community. According to different criteria, there are the following types of communities: (1) According to the classification of community functions, there are economic communities, political communities, cultural communities, military communities and special communities.

2) According to the organizational form within the community, there are whole communities and partial communities. (3) According to the interaction of community members, there are concrete communities and abstract communities. (4) According to the economic structure, population density, and population agglomeration scale, there are rural communities, urban communities, and market town communities (or urban communities).

Largest plain: Amazon plain (Brazil).

Highest plateau: Tibetan Plateau (China).

Largest basin: Congo Basin (Africa).

Longest land mountain range: Andes (7,500 km long)Longest submarine mountain range: Mid-ocean ridge (80,000 km long)Longest mountain system: Cordillera (10,000 km).

A basin, as the name suggests, is like a large basin placed on the ground, so people call the basin-like terrain with high (mountains or plateaus) around it and low (plains or hills) in the middle as a basin. The largest basin on Earth is in the middle of the East African continent, called the Congo Basin or Zaire Basin, which is about 1 3 times the size of Canada. This is an important agricultural region in Africa, and the edge of the basin is rich in mineral resources.

Hills are one of the world's five major land basic terrains, which refers to the undulating and gentle surface of the earth's surface, with an absolute height of less than 500 meters and a relative height of no more than 200 meters, and a slope combination composed of various rock types. The slope is generally gentle, and the cutting is broken, without a certain direction. From north to south, China mainly has the hills of western Liaoning, Huaiyang and Jiangnan.

There are loess hills on the Loess Plateau. To the south of the middle and lower reaches of the Yangtze River, there are Jiangnan hills. The hills on the two peninsulas of Liaodong and Shandong are also widely distributed.

The altitude is generally more than 1000 meters, the area is vast, the terrain is open, the surrounding area is bounded by obvious steep slopes, and the relatively complete large-scale uplift area is called the plateau. The main difference between the plateau and the plain is the higher altitude, which distinguishes it from the mountains with a complete large area of uplift. The plateau is known as the "stage of the earth", which is formed in the long-term continuous large-scale crustal uplift.

Some plateaus have a broad and flat surface, and the terrain is not very undulating; Some of the high principles are undulating and the terrain changes greatly. The highest plateau in the world is the Qinghai-Tibet Plateau in China, and the largest plateau is the Antarctic Ice and Snow Plateau. The most essential feature of the plateau is that the terrain is relatively low in elevation and quite high in altitude.

Plateaus are widely distributed, and together with the basins they surround, they occupy about 45 percent of the Earth's land area.
