The origin of the name
In the article "The Origin of Siberian Place Names" by Bohan and Feng Jiasheng, it is believed that Siberian place names come from Xianbei. Xianbei lived in Siberia in ancient times, and Xianbei in China's history books is just a scattered surname of this nation's southward migration. Siberia has a vast territory, starting from Urals Mountain in the west, east to Chukchi Peninsula, and facing Alaska across the sea. Siberia is transliterated from Chinese, SIBERIEN from German, SIBERIE from French and SBERIA from English. It is obviously transliterated from English, so it is the latest noun. It is not easy to find historical clues with the latest nouns, so we must come up with an older name. Siberian Russian is счбчр, which comes from Latin SIBIR. This is the result of writing in German, French and English. Russian SIBIR is transliterated from a nation called Sibir, which first appeared in Russian in 1483. The Tsar began to call himself Emperor of Siberia in 1563. After the demise of Xibe nationality, several cities and regions they left behind were also called Xibe nationality, and finally expanded into modern Xibe nationality or vast areas of Siberia. Bowen has a detailed discussion, so I won't repeat it here.
