Recently, many people have been fascinated by Russia, especially the slogan "Ulla" at the Russian military parade. He thought that the national slogan of the fighting was very imposing, so he changed the law to interpret the origin of the word "Ula".
Some experts believe that it was left over from the Mongol expedition to Russia, while others believe that it is the slogan of the Turkic charge. Not to mention that this statement is not reliable, as far as I know, the Golden Horde established by the Mongols in Russia did not have much contact with our Yuan Dynasty. Sometimes relations between the khanates are still very tense, so we don't have to put gold on our faces.
This expert is also very powerful, and the Russians are obviously the Ural nation. Native to the Ural Mountains, the mother river is the Ural River. People shouting "Ulla" has become a foreign language, and I am really convinced of these experts and scholars.
Genghis Khan's Mongol dynasty, though powerful, was ultimately a fishing and hunting people, and it was impossible to assimilate the natives. There are many Tatars in the Russian Far East, and I have not seen any achievements in Russia's recent history anyway, but have been completely marginalized by Russia.
Therefore, I think that scholars should not take theories to educate people, but should persuade people with factual evidence. For example, this simple slogan, something that is obviously very easy to understand, has been deliberately complicated. Everyone thinks I'm right or the experts are right, so feel free to leave your comments in the comment area.
