Long before the establishment of the Yuan Dynasty, the Mongols repeatedly used troops against Goryeo. From 1231 to 1259, the Mongols invaded Goryeo seven times. Although it caused huge losses to Goryeo, due to the desperate resistance of the Goryeo military and civilians, the Yuan rulers realized that it would not be easy to completely conquer Goryeo. Although the Goryeo royal family was able to survive due to the surrender of Ganghwa Island, up and down the peninsula, where the Mongol Iron Horse passed, the Lu Society was empty. Goryeo had long been trapped in the point where it could no longer fight. In this case, marriage becomes the best choice for both parties.
Kublai Khan agreed to this request and married his daughter Princess Dachang of the State of Qi (surnamed Bo'er Only Jin, named Kudu Lu Jieli) to the then King of Zhonglie. The marriage was still relatively smooth, and the belly of the eldest princess was also very contentious, and soon gave birth to a son, who was later King Zhongxuan of Goryeo. After this marriage, the Mongols began to regard the Korean royal family as their own, no longer seeking to overthrow by force, and often aided food and supplies. More importantly, the power of the Joseon Dynasty stabilized.
Princess Anping's name for marriage is to recruit a horse, not to marry and kiss. Princess Anping had a bad temper and often insulted officials and ministers, including the chancellor, and the dignitaries were trembling when they saw Princess Anping, lest they be scolded by Princess Anping. In 1279, when Goryeo was starving, the Yuan Dynasty gave Goryeo supplies to tide over the difficulties, and Goryeo at that time was somewhat similar to the Western kingdom, and the royal family liked to marry close relatives. The arrival of Princess Anping of the Yuan Dynasty greatly improved the situation and consequences of the marriage of close relatives.
The fate of the subsequent Goryeo kings was almost the same as that of Wang Meng, and some were even inferior to Wang Meng. Although the king of Goryeo married a Princess of Mongolia and was able to stop the war, it was a good thing for the people, and then this was a miserable situation for the King of Goryeo, who had to endure being suppressed or even humiliated for a long time, and it was normal to say that despair was normal, but it was just sullen, that was really a big heart.
