According to your topic, under the proposition of "now", it should be regarded as Mongolian and China. They are dual nationals.
He was born in Mongolia today, but he ruled the Central Plains generation after the battle. At that time, the central government was located in Beijing, so he also obtained China nationality.
For example, for example, if China is not unified but divided into two countries, such as North Korea and South Korea, should everyone in China's history be certified as nationals? We don't need to study historical figures. European historical research is much more open than ours. They only said when so-and-so came from, not which country he came from. Only people born today have this necessity.
Einstein: Did anyone say he was German? It may be helpful for you to have a look at his life.
Einstein (1879- 1955) left German citizenship in 1895, became a Swiss citizen in 190 1 year, and became a German citizen in 19 18 year. At this time, he has dual nationality. Joined American citizenship, but retained Swiss citizenship until his death. So it is wrong for some people to just say that he is German-American. When he died, he was a Swiss and American citizen, and he should be a Swiss and German-American.
1895, he left German nationality to escape military service, because Germans have the obligation to perform military service, and he hates war. 19 18 years, he has returned to Germany, so he joined German nationality again, so the Nobel Prize in 192 1 year belongs to Germany. Although he has dual nationality, he is obviously German.
1940, he couldn't get rid of German citizenship, because the Nazis no longer regarded Jews as Germans, and he was in the United States at that time, so he joined American citizenship.
Throughout his love life, he never paid attention to his nationality, nor did he really belong to any country, so it is inappropriate to say that he belongs to any country. Relatively speaking, Germany, as his motherland, is more confident to say that he is a German, but generally books do not mention his nationality and say that he is a citizen of the world.
In our history books, the concept of Yuan Dynasty is mostly used.
For example, the political parties in Taiwan Province Province once said that they would revise the history books (limited to Taiwan Province Province, of course), and the history outside Taiwan Province Province was foreign, which caused the great earthquake in Taiwan Province Province. "Has our founding father (Sun Yat-sen) become a foreigner?"
Therefore, in China, we define Ji as a native of China. Other countries in the world have different definitions, but China is less, because he was not born in China now. But his descendants were born in China and China, and his father was an immigrant.
Finally, Genghis Khan's court found that:
