1, "China" has a long history. Before the Revolution of 1911, it was a long feudal monarchy, with three dynasties of Qing, Ming and Yuan ... but it was all "agricultural civilization". 2. The 200-year history of "America" is the founding event of "America". Before that, the first settlement in Virginia established the "Mayflower" that crossed the ocean … European civilization … Rome … Greece … Crete … inherited the western civilization. It can be seen that this is a kind of conceptual confusion compared with the five thousand years in China and the two hundred years in the United States. The mistake of common sense. A distorted view. For example,-1, "Mayflower" landed in Plymouth, and more than ten years later, "Harvard University" was established. The constitution they formulated 200 years ago is the crystallization of western political wisdom from the classical Greek city-state era to the18th century. Just like some border areas in China, they were developed late, but most of the residents there were immigrants from the early development areas of the Central Plains. 2. Among the ancient civilizations in the world, Mesopotamia civilization, Egyptian civilization and western civilization (Minoan civilization) were about 1000 years earlier than Chinese civilization by about 2000 years. Textual research shows that the development level of western civilization was higher than that of China in most periods. Minoan civilization was equivalent to our Xia Dynasty when it built magnificent palaces and created exquisite murals, but our Xia Dynasty is still under study today. About two "dark ages" in western history, namely12 ~ 8th century BC and 5 ~10th century AD, the development level of Chinese civilization was higher than that of the west. But in these two periods, foreign invasion interrupted the normal development of western civilization ... Summary-1. Although China has a long history, it is an agricultural civilization. Although the United States is a young country, it is a modern industrial civilization and a civilization in the information age.
