The traditional name of China comes from English.

This can be traced back to the "Silk Road" era.

At that time, China's silk and porcelain were recognized and praised by many European countries. At first, there was no English translation from China, and China was widely used as the word porcelain. Later, taking this word as the name of the country shows the degree of appreciation of Chinese porcelain by foreigners.

As for Chinese, this is a distortion of English vocabulary. Because English is rooted in Latin, a word can have many variants, which is convenient for people in need.
