Which country is China most similar to?

In ancient times, there was only one country that could be compared with China, and that was the Roman Empire. In the contemporary 21st century, the only country that can compare with China is the United States.

The three elements of a country include: regional environment, population composition, and political system.

Let’s look at the geographical environment first: China and the United States both cover an area of ??more than 9 million square kilometers. Moreover, the latitude range is similar, one is in the Eastern Hemisphere and the other is in the Western Hemisphere. The climate is very similar; the terrain is higher in the west and lower in the east; the products are also similar. The crops that can be grown in the United States can also be grown in China, and the animals that can be raised in China can also be grown in the United States. Can be cultivated.

Look at the population composition: The United States is a multi-ethnic country or a country composed of immigrants; the current president of the United States, Obama, is a descendant of African immigrants. China is also a multi-ethnic country with 56 ethnic groups. In fact, China has been a country composed of immigrants since ancient times. China was called the Central Plains in ancient times. That is to say, many ethnic groups often competed in the Central Plains, and then continued to integrate. These integrated immigrants established countries in the Central Plains. It was not until the Han Dynasty that the surrounding ethnic minorities were called Han people. On the surface, most Chinese people are Han people. In fact, the reason why the Han people are called Han people is just because they speak Chinese and practice Chinese characters. After researching "Hundred Family Surnames", it is not difficult to see that the Chinese are actually the descendants of immigrants. The Han people have the most complicated genes, and there are no pure-blooded Han people at all. Therefore, the oldest immigration country in the world is China. China has at least 4,000 years of immigration history. And to this day, the Chinese still retain the gene of being good immigrants. How else to explain the phenomenon of Chinese people spread across five continents? It can also be seen from the Chinese idiom "36 plans are the best plan" that the Chinese people have a natural tendency to immigrate. It was only under the closed-door policies of the Ming and Qing dynasties that the Chinese people's tendency to immigrate was restricted. In the 19th and early 20th centuries, when the Chinese government exported its labor force, many Chinese immigrated to Europe and the United States, and some coastal fishermen immigrated to Southeast Asia. The immigration history of the United States is just over 300 years ago. The first people were ethnic groups from northwest Europe, then people from all Europe, and then Asians and Africans. . . Now, people all over the world want to immigrate to the United States. In the ancient Tang and Song Dynasties, people all over the world wanted to immigrate to China. Why? it goes without saying. . .
