Zhu Di, the founding emperor of the Ming Dynasty, made five northern expeditions: he completely defeated the remnants of the Northern Yuan Dynasty.

After Beiping was designated as Beijing in the first year of Yongle (1403), Judy planned to move the capital. So he sent people to build canals to control floods and make the economy of the Ming Dynasty develop rapidly. At that time, the state treasury was well-off, and besides transporting millions of stones from Beijing every year, there were many warehouses in various counties. But at this time, Japanese pirates were very arrogant, and they often plundered merchant ships and people along the coast. As early as when Kublai Khan was in Yuan Shizu, the Yuan Dynasty sent an expedition of100000 people to crusade against Japan, but it was wiped out by a storm. During the Ming Dynasty, Japan was divided into the north and the south, and the southern forces often committed atrocities in the coastal areas of the Ming Dynasty. Zhu Yuanzhang once warned Japan, but the Japanese turned a deaf ear. In the face of arrogant enemies, Judy showed no mercy. He sent heavy troops to wipe out the enemy and dealt a heavy blow, which significantly improved the law and order along the coast of China.

According to legend, after Yuan Shundi fled to Mobei, he died in Yingchang in the fifth year of Hongwu (1370). After several generations, Mongolian aristocrats were divided into three parts: Tatars, Wala and Wuliangha. The Tatar is the strongest of the three. They invaded the Ming border from time to time. On the one hand, Zhu Yuanzhang made friends with Mongolian nobles, on the other hand, he adopted an active defense policy. From Jiayuguan along the Great Wall into the Liaodong-Yalu River line, the establishment of a nine-year border town, that is, "nine borders." After Emperor Chengzu of Ming Dynasty succeeded to the throne, he followed Zhu Yuanzhang's policy of combining rigidity with flexibility, and sent 100,000 and 500,000 troops to the north to levy Tatars in the seventh year of Yongle (1409) and the eighth year of Yongle (14 10) respectively. Once every eight years is a personal adventure. After two expeditions, the Tatar surrendered and paid tribute to horses in the Ming Dynasty every year. Of course, the Ming dynasty also gave a generous reward and named its leader Arutai as King Ning.

After Tatar became a vassal, the Walla Department became strong and stationed troops in the north, posing a powerful threat. Therefore, Judy decided to go on a personal expedition again and conquer the Walla tribe.

In the 12th year of Yongle (14 14), the Ming army went to the frontier and arrived at the mouth of the Three Gorges in June of that year (now northwest of Duolun, Inner Mongolia). After careful investigation, Judy learned that the enemy was nearby, so he ordered the whole army to get ready. When the Ming army went to Hulan, it suddenly lost its temperature (east of Ulaanbaatar, Mongolia), and Judy suddenly saw the dust flying ahead. It turned out that Ansiba and Mahamu sat in a chariot and commanded hordes to kill them. Judy immediately asked the Ming soldiers to rush into the enemy line in three ways, and then assisted with artillery. Mongolian cavalry are not vulnerable, they are brave and good at fighting, and they have not let the Ming army take advantage of them. Seeing the uncertain situation, Judy immediately took the lead in fighting behind enemy lines. The emperor takes the lead, how can he stand by when the enemy arrives? As a result, the Ming army leaped like a dragon and a tiger, instantly turning the tide. Mahamu was defeated and fled, and Judy led his troops to pursue him. Finally, discouraged by the emperor's grandson Zhu Zhanji, Judy stopped pursuing and ordered to return to Beijing.

Mahamu suffered heavy losses and had to bow to the Ming Dynasty. However, Arutai and Mahamu have always been at odds, and they often denigrate each other in front of Judy. Judy wants to use their contradiction to control the two tribes, so he ignores these slanders. Soon, Mahamu died of illness, and his son still paid tribute to him after Ming Chengzu abdicated. Arutai lost his opponent and gradually became arrogant. Not only did he fail to pay tribute on time, but he also detained the envoys of the Ming Dynasty and led troops to make waves at the border of the Ming Dynasty.

Judy thinks that if we don't conquer Mongolian aristocrats early, we will definitely leave behind future troubles. So, regardless of the opposition of ministers, in September of the 18th year of Yongle (1420), we decided to move the capital to Beijing in the first month of next year and change it to Beijing as the capital. Now the capital is Nanjing. At this time, the construction of Beijing Palace and the transformation of Beijing City have been completed. However, many ministers considered that the grain and grass near Beijing were not enough to support the Ming army after moving the capital, so Fang Bin, the minister of the Ministry of War, Wuzhong, the minister of the Ministry of Punishment, and Xia Yuanji, the minister of the Ministry of Housing, expressed their views in succession to prevent Judy from moving the capital. Judy will certainly not listen to their opinions, and these ministers will not escape jail. Later, Judy told Zhang Ben, assistant minister, to do everything possible to collect enough rations.

In the twentieth year of Yongle (1422), Judy once again made a personal expedition to Mongolia. This time, the Ming army only transported grain and grass, using 340,000 donkeys,177,500 vehicles and 235,000 civilian workers. * * * Carrying 370,000 stone grain costs the country a lot of manpower, financial resources and material resources. Of course, this also shows the strength of Yongle Dynasty. This is consistent with Judy's constant dispatch of ocean-going fleets to expand to the west.

Besides, Judy led the Ming army to Jiming Mountain (now Huailai North, Hebei Province). I heard that Arutai had fled to the north, so all the soldiers suggested that the army should go deep behind enemy lines and give the enemy a fatal blow. Knowing that Arutai was scheming, Judy ordered the army to set out from Kaiping (in Duolun County, Inner Mongolia) and pass through Yingchang to take the enemy's headquarters by surprise. In June of that year, the Ming army arrived in Yingchang, and Arutai saw the army coming and continued to escape. Judy said wily, "it's true that he escaped, but in order to prevent him from playing tricks, we should burn the rations he left behind and then attack the five grains and three flavors." Wuliangha Sanwei is three autonomous regions established in the northeast of Ming Dynasty, which are divided into Duoyan Wai, Taining Wai and Fuyuwei.

After Arutai arrived at Wuliangha Sanwei, the leaders of Sanwei expressed their willingness to help him. At this time, Judy analyzed the war situation and said: "Arutai fled at this time, which just isolated Wuliangha, and we took the opportunity to break him in one fell swoop. Immediately, the Ming army divided the soldiers into five roads and besieged Wuliangha. Wuliangha led tens of thousands of troops to Quxier River (a tributary of the upper reaches of Taoer River today). As a result, he accidentally fell into the swamp, and Judy saw that the situation was not good and ordered the cavalry to kill him. Wuliangha's troops were in chaos and immediately collapsed. At this point, the Ming army crossbowman who had been lurking in the Woods also pulled the trigger. In an instant, thousands of arrows were fired, only the screams on the field and the screams of people broke out. The Ming army went all out to destroy Wuliangha's lair in one fell swoop, and Judy won again.

In July of the 21st year of Yongle (1423), Judy heard that Arutai had brought troops again, and said with a smile, "Arutai thought I went out in person last year, so I won't go this year. He really underestimated me. " After that, Judy was angered again and started her third personal expedition. On the way, the Ming army suddenly met Arutai's men and surrendered, and learned that Arutai had been defeated by the Walla tribe and was fleeing everywhere. Judy was very happy and ordered the army to move on. When the Ming army arrived at Shangzhuangbao, Prince Tatar also led the crowd to surrender. Judy was overjoyed and immediately made him the king of loyalty and courage, giving him the name of "Jinzhong", and then led the army back to the south.

In the 22nd year of Yongle (1424), Judy heard that Arutai had attacked again. Brave Wang Jinzhong asked Cheng Zu to send troops and volunteered to fight for the striker, so Judy began his fourth personal expedition in April. This time, Judy went through all kinds of hardships, climbed mountains and searched the valley, but couldn't find any trace of Arutai. Finally, he had to say helplessly: "The army is out of town, people are exhausted, and food and grass are limited. Why don't you quit for a while? " "Soldiers in June, and out of Mobei in July. On the way back from the fifth expedition, Judy suddenly fell ill in Yumuchuan (now northwest of Duolun, Inner Mongolia) and couldn't sleep at night. When I closed my eyes, I saw countless ghosts coming to kill him. When he was sober, he knew that he didn't have much time left, so he called Zhang Fu, an English public servant, and ordered him to give the testamentary edict to Prince Zhu Gaochi. Soon, Judy stopped breathing in the torture of illness. At the age of sixty-five, he was honored as Emperor Wen, and the temple name was Taizong (in the seventeenth year of Jiajing, the temple name was changed). Funeral is like the legacy of Emperor Gao. After Judy's death, Prince Zhu Gaochi succeeded to the throne in August of that year, and the following year was changed to the first year of Hongxi, known as Emperor Renzong in history.
