After Kublai Khan destroyed the Song Dynasty, in order to maintain his rule and adopt Liu's suggestion, Liu chose a Chinese title from the classic Book of Changes. The title is "Big in Gan Yuan" and the abbreviation is "Dayuan".

Before Dayuan, such as the historical drama we filmed today, the front of the dynasty was magnified, and it was "lazy" and did not understand history at all. It's your turn to speak, Dasong, Datang and Dahan. Although the word was added at that time, it was not "big" but "strong Han" and "prosperous Tang Dynasty". Even the Song people said it was "strong Song" and so on.

Plus the "big" dynasty, there are only Dayuan, Daming and Daqing. Compared with the real thing, the names of Yuan, Ming and Qing are inaccurate, so it is necessary to add "Da". Because the rulers at that time absolutely thought their country name was inviolable, they omitted it.

Then again, why is Kublai Khan's founding name "Dayuan"? As we all know, the ancient country name of China was either "surname". Such as "Zhou" and "Qin". Either a title or a fief, such as "Han" (Liu Bang was named Hanwang before he proclaimed himself emperor), "Wei" (Cao Cao was named Wang Wei, and Cao Pi succeeded to Wang Wei after his death, and later proclaimed himself emperor), "Tang" (Tang Guogong of the Sui Dynasty before Li Yuan proclaimed himself emperor) and "Song" (he was our envoy in Songzhou and was given a yellow robe later).

But what about the Mongols? He used to be a nomadic shepherd ... he had no title. What should I do? As a result, Liu had an idea. Like I said, choose from the classics. Great Gan Yuan, "the vast earth creates everything", which he thinks is particularly great. Take the beginning and end to become "Dayuan". Therefore, the "big" of Dayuan cannot be explained separately, but must be explained in "big and dry", which does not mean "strong" or "great". I think it means "vast territory".
