1, Wula has no specific meaning in Russian, and is usually used as a modal particle to express strong feelings. Russian officers and men usually shout "Hula!" When charging. Often translated as "Long live!" The Soviet Union/Russia used to use "Ura!" During the military parade. The function of the slogan is similar to the military parade in China, which is "Hello comrades! Hello, chief! Comrades have worked hard! Serve the people! " The parade shouted.

2. Etymology: "Wula" is not a Russian word, but was introduced by Russians of other cultures. There are many theories about its origin.

3. A saying comes from "Tatar". Tatars mentioned by the ancients are not Tatars in Russia today, but refer to many tribes of Mongols. Europeans in the Middle Ages, including Russians, collectively referred to Mongols as Tatars. China also called "Tatar as Mongolia" in Biography of Ming History abroad. Warriors of medieval European countries were most afraid of their opponents in the war, that is, the nomadic people on horseback: Tatars. In many European novels describing medieval wars, we can see the description of this scene: the terrible "Ola" sound and the whooshing lasso sound suddenly sounded in the vilen, and everyone was pale and knew that the terrible Khan army was coming and the invincible shepherd army was coming. Khan Army, Shepherd Army and Tatar are all European names for Mongolian tribes. Since Genghis Khan's time, the marching slogan "Hurree" (pronounced "Wula") of Mongolian army is also the source of Russian "Wula" in later generations. Professor Jack Weatherford, an American national historian, pointed out that the word "Wula" was originally a declaration that the Mongolian army spread to many places in Europe and Asia in the13rd century. The ancient Russians who were oppressed by the Mongols for hundreds of years inherited the conquest declaration of that year: "Wula".

4. Another view is that "Wula" was originally the marching slogan of the German army, which originated from the word "Wula" in Highland German. The prototype of "Hurra" is "Hurren", which means "fast marching". After the introduction of the Russians, it extended to victory. Germany has long been the object of Russian military study in history, so it is very possible for Russia to introduce German military slogans.
