During the Kangxi period of the Qing Dynasty in the eighteenth century, a very interesting thing appeared in Beijing, every day there were soldiers dressed in Qing Dynasty soldiers on duty at the Dongzhi Gate of the Imperial Palace, but unlike other Qing Dynasty troops, these people were all tall foreigners with tall figures, straight noses, and blue eyes, who put on Qing Dynasty costumes, which looked a bit funny, and were incompatible with the scene at that time, how could the Qing Court have "Russian Janissaries?" "What's going on?

During the Kangxi Dynasty, with globalization and the expansion of Western civilization, in the fifth year of Shunzhi, that is, in 1649, a big brother named Woolangi crossed the Siberian region and came to China.
Wu Langgeri was a very good man who saw the wind and steered the helm, he saw the prosperity of Beijing, and quickly learned Chinese in China, took the opportunity to say a lot of good things about the Qing Dynasty when he met the Shunzhi Emperor, so that the Shunzhi Emperor had face, and the dragon's heart was very happy, so he was compiled into the Manchu military organization NiuLu and gave him the position of deputy chief.
Some white people in Russia heard that WuLangli was mixing well in China, with clothes and meat to eat, but they could only live in Siberia to nibble potatoes, and they could not help but envy Wulangri, and they came to defect, and the Qing court also did not refuse, and they were incorporated into the yellow flag and let them guard the Dongzhi gate of the imperial palace. As long as you serve the Qing court, then the benefits will be greatly dripped!
Originally, Shunzhi wanted to weave them into a single collar, but even in the Kangxi period, these numbers were only about a few dozen people, and they could not reach the establishment.
This continued until the 18th century, when the Russian Empire, which had expanded all the way west, began to border the northeastern region of China's Qing Dynasty, and some Russians set their sights on the rich lands of southern China, constantly sending bandits and soldiers to harass, plundering the Qing border, and once occupying the border town of Yaksa.
The Kangxi Emperor had repeatedly sent envoys to negotiate and warn the Russian Emperor, but these had no effect, so Kangxi decided to use force to completely eliminate the rebel forces in the border areas.
In 1682, Kangxi decided to personally patrol the border, and after making long preparations, liquidated the Russian bandits who harassed the border along the way.
At this time, those Russians who came to join the Qing Dynasty came in handy! Kangxi used them as translators to inquire about the Russian Empire, and through this extremely valuable information, the Qing army gradually uprooted the Stronghold of the Russian bandits in China, and Yaksa, occupied by the Russians, immediately became an isolated city surrounded by the Qing army.
In order to reduce unnecessary losses and sacrifices, these Russians collected by the Qing Dynasty played a role, and they were sent to persuade the Russians inside the castle to surrender, tell the policy of the Qing Emperor, see their compatriots and the current treatment, and the bandit army that insisted on the castle was willing to commit weapon surrender.
For the Russians who surrendered after this battle, Kangxi did not return them to their hometown in the north, but unified them into Beijing, which was a hundred people, and the problem of organization was finally solved, and Kangxi divided them into the fourth staff leader of the Manchurian capital with the yellow flag to rule and govern.
In fact, until here, we can see how clever Kangxi is, his purpose of recruiting Russians, and more importantly, to prevent the situation that will continue to fight with the Russians in the future, this kind of foresight is very necessary for the Tsarist Russia.
Later, these Russians also multiplied in Beijing and merged into part of China's ethnic minorities.
