After the establishment of the Ming Dynasty, although the Mongols lost their rule over the Central Plains, they still had great influence in the northern grassland areas. Many parts of the country, such as Shanxi, Shaanxi, Sichuan, Yunnan and Guizhou, are still in the hands of the rulers of the Yuan Dynasty, which has always been a major threat to the Ming Dynasty. In the fourth year of Hongwu, Aquamarine cut Shu from Fu Youde and Kemian. Five years from Xu Da to the north, first out of the wild goose gate, defeated Yuan soldiers in the chaotic mountains, and then defeated the river. In seven years, he was a handsome soldier, and he won fifty-nine people, including Li's Lord protector. Eleven years with Pinghou Xi for the western expedition, captured three ambassadors under his chief, and gained thousands of people. Next year, when the teacher comes back, he will seal the post of Yongchang, eat 2,500 stones and give the world coupons. In the autumn of the fourteenth year of Hongwu, Mu Ying built the Kunming Zhongyi Square, and Zhu Yuanzhang appointed Fu Youde as the general of Zhengnan, Aquamarine as the left vice president and Mu Ying as the right vice president. He rode 300,000 troops to Yunnan, and all the barbarians surrendered, and Yunnan was leveled. Mu Ying, Aquamarine and Fu Youde will gather in Yunnan to jointly announce the good news and make preparations for the aftermath. After reading Mu Yinggong's book, he ordered Mu to defend Yunnan. Since then, aquamarine has also been favored by Ming Taizu. In March of the sixteenth year of Hongwu, he called Nanshi back, and Mu Ying stayed in Yunnan. In the twenty years of Hongwu, Yuan Taiwei left Naha, occupied several golden mountains and invaded Liaodong repeatedly. Zhu Yuanzhang appointed Sheng Feng as the general, Fu Youde and Aquamarine as the left and right deputy generals, and led two hundred thousand Northern Expeditions. The Ming army succeeded in the "Battle of Jinshan" and surrendered to Naha, the general of the Yuan Army. However, after the decline of the Northern Yuan Dynasty, several Mongolian separatist regimes appeared in the former Yuan Dynasty, and Nabachu was only one of them. Naha's surrender to the Ming Dynasty can only be said to be the surrender of the Ming Dynasty to one of the most powerful Mongolian separatist regimes, which relieved the threat to the Ming Dynasty, but it does not mean that all Mongolian ministries surrendered to the Ming Dynasty.
