Why didn't the Ming dynasty even confiscate the western regions, which was known as the world's number one power?

Qin Shihuang built the Great Wall, built a military fortress based on the Great Wall, and sent Meng Tian to station 300,000 troops in the Tunhetao area to defend against the Xiongnu invasion.

Emperor Wu of the Han Dynasty took the initiative to attack strategically, opened up territory and established immortal and brilliant martial arts: breaking the country in the south, destroying Dawan in the west, surrendering the western regions and defeating the Xiongnu. The price paid: the savings of the two generations of Wenjing have been spent, the state treasury is empty, the people are poor, and the hukou is halved. All industries related to the national economy and people's livelihood are monopolized by the government. If you sell officials and titles, you can use money to atone and send a letter of accusation.

Liu Xiu, Emperor Guangwu of Han Dynasty, mainly took preventive measures, and all the people guarding the border moved to the mainland.

In the Tang Dynasty, Li Shimin, Ye Li, Wu Zetian and Emperor Xuanzong of the Tang Dynasty adopted the policy of combining hard and soft, taking the lead in picking holes, then providing moral services: taking the lead in knocking down the discontented, appeasing those western countries that were politically friendly to the Tang Dynasty, and exerting the influence of economic and cultural soft power to achieve the effective goal of defeating the enemy without fighting.

In the early Ming Dynasty, there were East Chagatai Khanate and Timur Empire in the Western Regions. When the Timur Empire was strong, there was no military force from Europe to India to stop Timur's expansion, and it was also a fiasco in Ottoman Turkey in Central Asia.

During the Yongle period, when the Ming Dynasty was most prosperous, Timur stepped up preparations for an expedition to the Ming Dynasty. Unfortunately, Timur's son's vanguard had just set off when Timur died halfway. There is reason to believe that Timur will not die, and he will have a big battle with the Ming Dynasty. Who will die is still unknown. During the Yongle period, Judy was always facing the threat of the restoration of the Northern Yuan Dynasty.

Chang Yuchun, Xu Da and Mongolian fighters confronted each other in Gansu, and Aquamarine pursued the Northern Expedition to Lake Berger. Ming Chengzu made five northern expeditions, and Zheng He's voyages to the West were invincible. Of course, the difficulty of transportation and supply in the farming era can be imagined, the consumption of national strength is amazing, and the nomadic people come and go without a trace.

However, the cleverness of the Ming people lies in that he used Liaodong to outflank Mongolia, and the northeast was close to the political center of the Ming Dynasty, which was geographically close. Coupled with the loyalty to North Korea, through hundreds of years of continuous immigration and development, the northeast region was gradually digested, forming an arc encirclement, Ming firearms were gradually popularized, and the cold winter of nomadic times has arrived.

As soon as the threat of the Mongolian plateau disappeared, the Ming Dynasty naturally had the spare capacity to govern the western regions, which was the recovery of the homeland of Han and Tang Dynasties in history.
