Don´t cry like a baby. You should better know your history.
Mongol invasion of China
The Mongol invasion of China spanned six decades in the 13th century and involved the defeat of the Jin Dynasty, Western Xia, the Dali Kingdom and the Southern Song, which finally fell in 1279. The Mongol Empire under Genghis Khan started the conquest with small-scale raids into Western Xia in 1205 and 1207.[1] By 1279, the Mongol leader Kublai Khan had established the Yuan Dynasty in China and crushed the last Song resistance, which marked the onset of all of China under the Mongol Yuan rule.
This was the first time in history that the whole China was conquered and subsequently ruled by a foreign or non-native ruler,[2] compared with the Manchus (who established the Qing Dynasty) who did so a few centuries later.

According to the logic of this article:
[Germany was conquered and subsequently ruled by a foreign or non-native ruler - Prussia.]
Since when did Prussian invade "Germany" themselves, and how could Mongol invaded a country which is not even existed during that period. These make no sense at all.
Besides Manchus and Mongol are both native of China.
And please don't take Outer Mongolia as your point, since I always mention:
1. More than half of Mongolian around the world are Chinese;
2. The cradle of Mongolian is in China;
3. The direct posterity of the Great Khan (Golden Family) are all Chinese (not Outer Mongolian);
4. Mongolian were founders of the Republic (Modern China).
5. the main ethnic of Modern Mongolia, Khalkha, were not even belong to the Mongolian family during the Yuan Dynasty.
You admitted Mongolian ruled you in Yuan Dynatsty, you were slaves of them. Good. Mongolia is today independence state.
We were all slaves under the ancient Monarchy.
Mongolian are part of the Chinese ethnic group, they established a great country - Yuan Dynasty. The rulers are Mongolians, but various ethnics officers (Han, Westerns...) can be found everywhere. Mongolian rulers even try hard to learn the "Middleland culture" (Mainly Han culture).
Macedonia is also an independence country, but that doesn't mean that Greek people will be pleased to hand over their history to "Macedonia".
