There are Koreans and Russians in China, but is there a China in the United States?

At this point, I must clarify with the landlord that there is no Han nationality in the United States, Han nationality does not belong to the United States, Chinese overseas Chinese, and Chinese are not Americans. As for China, why are there Koreans and Russians? That's because the empire established in ancient China was vast. Until the Ming Dynasty, a vast area of Russia was carved up by the Ming Dynasty. In the Yuan Dynasty, the Russian empire perished, which led to the partial eastward movement of Russians to China and integration with the Han nationality, which is indispensable for our Chinese nation. Koreans have always been a vassal state of China. Some Koreans are dissatisfied with the corruption and weakness of this country. A few rich Koreans immigrated to China and gradually formed Koreans. Some Koreans emigrated because of the war. Both the Sui Dynasty and the Tang Dynasty sent troops to Korea, which led to people's displacement and migration to China.
