Cold knowledge, why are the appellations in ancient China all one word? What is the reason?

First of all, we should start with the traditional culture of China. You know, when Chinese characters were first created in China, there was an idea that the specifications and status represented by one word were higher than that of two words, so was the name of the country, which made the name of one word more respectable than that of two words. However, this habit is invisible in the cultures of some ethnic minorities, so it is also a difference between Han nationality and ethnic minorities to some extent.

Secondly, we should know that Qin was the first feudal dynasty in ancient China, and the title of the Qin dynasty was a Qin character at that time, which led the later Han dynasty to learn this practice of the Qin dynasty and set the title as Han, so this habit continued and was adopted by many later dynasties, and in the cognition of the rulers of many later dynasties, they would think that only such a title was truly orthodox.

But there was a habit at that time, that is, to put a big character in front of the country name of this word, such as Daqin Dahan and Daming. To show China's imposing manner.

In addition, a word can be read more fluently and easily accepted by the people, and it can also represent the will of this dynasty. Imagine that if the title of this dynasty is defined as a few words, it will give people a sense of neither fish nor fowl. For example, the Taiping Heavenly Kingdom Movement of the Rebels in the late Qing Dynasty was titled Taiping Heavenly Kingdom by Hong Xiuquan at that time, so it was awkward to read, and the Taiping Heavenly Kingdom did not last long.
