In the face of foreign invasion, China's dynasties have never been cowardly, using powerful armies to directly fight back against the enemy and show the national integrity that the Chinese nation should have, and it is this unyielding integrity that has made the Chinese nation stand tall in the world for five thousand years.
China in the 14th century was in the midst of a war, and this was the war against the Yuan Dynasty led by Zhu Yuanzhang. The Mongol Empire was vast, and its territory was not only in China, but also in Central Asia, Europe and other places.

With the brutal rule of the Mongols, a wave of rebellion against the Mongols began to be set off everywhere, with Zhu Yuanzhang in China and Timur in Central Asia.
After Zhu Yuanzhang established the Ming Dynasty, Timur befriended the Ming Dynasty and formed an alliance to jointly rebel against the Mongols. Zhu Yuanzhang attacked the Mongols in the north in China, drove them out of Cyprus, and realized the unification of China.
Tamerlane overthrew the Chagatai Khanate in Central Asia, and then went around conquering to establish the huge Timurid Empire, and the Ming Empire became the world's two great powers.
After the establishment of the Ming Empire, Zhu Yuanzhang decided to open up the Western Regions, recover the western regions, and let them be included in the territory of China. Therefore, Zhu Yuanzhang sent emissaries to the countries of the Western Regions to publicize the national prestige of the Ming Dynasty.
Tamerlane's imperial wars were still going on, expanding everywhere, and in order to cut off the connection between the Ming Dynasty and the Western Regions, he detained the emissaries who came and went. As Timurid's ambitions swelled and the Timurid Empire expanded, he targeted the Ming Dynasty.
At this time, the Ming Dynasty had just finished a war, and its national strength was damaged, and it was during the Ming Dynasty's Zhu Di period.
Timur, as the founder of the world power, decided to lead 200,000 troops to attack the Ming Dynasty, and it was enough to let 200,000 people take China. It is a pity that history did not let Timur and Ming Chengzu meet, otherwise a world war would have appeared on the stage of history.
During Timur's crusade, he died of illness, leaving 200,000 people in a hurry to return home, and a war ended in an instant. The Timurid Empire was in crisis, and after his death, his sons began to fight for power and profit, and Finally Shaharu succeeded to the throne.
At this time, Ming Chengzu heard that Timur was going to attack the Ming Dynasty, so he conducted a military exercise and invited emissaries from various countries to see the exercises of the Daming army and publicize the national prestige of daming.
Among these many emissaries naturally included Timur emissaries, when Timur emissaries saw the mighty and powerful Ming army, they immediately reported to Shaharu and said that not to mention 200,000, even if it was tenfold, two million troops could not take the Ming Dynasty, and the Ming army was very strong.
Therefore, Shaharu dispelled the idea of attacking the Ming Dynasty, and instead made good friends with the Ming Dynasty and resumed friendly exchanges between the two countries.
