The King of Yan refers to Zhu Di, the founder of the Ming Dynasty. Zhu Yuanzhang was the King of Yan when he was in power! King Yan's sweep to the north refers to Ming Chengzu's Northern Expedition

After Ming Taizu Zhu Yuanzhang overthrew the Yuan Dynasty and established the Ming Dynasty, the remaining forces of the Yuan Dynasty retreated to the Mongolian Plateau, known as the Northern Yuan Dynasty in history. Later, Mongolia split into Tatar, Oara and Ulyankha, posing a threat to the Central Plains. After Ming Taizu's Northern Expedition, Ming Chengzu, who came to the throne, in order to completely eliminate the remaining forces of the Yuan Dynasty, Zhu Di personally led the Ming army in the Northern Expedition starting in 1410 AD (the eighth year of Yongle). In this Northern Expedition, the Ming army defeated 50,000 Mongolian cavalry in the battle of Feiyun Mountain, and the Tatars in Mongolia declared themselves vassal and paid tribute to the Ming Dynasty.

In 1413 AD (the eleventh year of Yongle), Emperor Yongle granted the title of King Hening to the Tatar Khan Arutai. Then the Ming army entered Qinhu Mountain and carved the inscription on the huge stone as a stele: "Hanhai is Tan, Tianshan is E".

In 1414 AD (the twelfth year of Yongle), Emperor Yongle launched the second Northern Expedition, defeating the Oara general Mahamu in Hulan Huwen (southeast of present-day Ulaanbaatar, Mongolia), and pursued him to Tula River, Mahamu fled. After Wala was defeated, Emperor Chengzu of the Ming Dynasty issued an edict to the world.

In March of 1422 AD (the 20th year of Yongle), Chengzu of the Ming Dynasty led his army from Beijing to personally conquer the Mongolian Arutai troops, which was the third Northern Expedition. The Ming army marched northeast through Kaiping and found a large amount of baggage from the Alutai tribe on Kuoluanhai North Road. They sent troops to burn it and collect their livestock. On the way back to the army, Uliangha rebelled against Arutai and defeated him.

In July of 1423 AD (the 21st year of Yongle), the fourth Northern Expedition was launched, and Alutai was once again personally conquered. I heard that Arutai was defeated by Wala, and the army was garrisoned but could not advance. In October, he accepted the surrender of Yexian Tuqian at Shangzhuang Fort, named Zhongyong King, and named him Jinzhong. In November, the class teacher returned to the court.

In the first month of 1424 AD (the 22nd year of Yongle), the Tatar tribe invaded the border, and Zhu Di organized the fifth Northern Expedition.

The five Northern Expeditions further weakened the power of Mongolia and maintained peace on the border of the Ming Dynasty. Later, Chengzu also died of illness on his way back to the Ming Dynasty after winning the fifth expedition.
